# The 1931 murder of Julia Wallace in Liverpool, with its famous “Qualtrough” phone-call alibi, is so evenly balanced between guilt and innocence that it is often called the perfect unsolvable crime

**No verdict.** The core event is beyond dispute: Julia Wallace was beaten to death in the front parlour of 29 Wolverton Street, Anfield, Liverpool, on the evening of 20 January 1931. What has never been settled is who did it. Her husband, the insurance agent William Herbert Wallace, was convicted at the Liverpool Assizes in April 1931 and sentenced to death, then had his conviction quashed weeks later by the Court of Criminal Appeal, the first time a murder conviction was overturned in England on the ground that the verdict “cannot be supported, having regard to the evidence.” No one else has ever been charged. A strange telephone call the night before, luring Wallace across the city to a street address that did not exist, sits at the centre of the puzzle: it either was his own manufactured alibi or was the trap laid by the real killer. Every party is long dead, the file is closed, and this page reports the mystery without asserting who was guilty.

Category: Unsolved Crimes & Disappearances · Era: 1930s · First circulated: The mystery took hold immediately after the killing in January 1931 and hardened into a genuine unsolved-crime legend across the 1930s; crime writers and lawyers have debated it ever since, with a named alternative suspect surfacing publicly in 1981. · Believed by: The status as a classic unsolved murder is close to universal among true-crime writers, criminologists, and lawyers; opinion splits sharply between those who think Wallace was a wronged innocent, those who still suspect him, and those who back a later-named suspect. No side commands a consensus.

## Summary
On the night of 19 January 1931, a telephone caller giving the name R. M. Qualtrough left a message for the Liverpool insurance agent William Herbert Wallace at his chess club, asking him to visit an address the next evening to discuss business. The following night Wallace crossed the city by tram in search of 25 Menlove Gardens East and found that no such street existed. He returned home to find his wife, Julia, battered to death in the parlour. Wallace was tried, convicted, and sentenced to hang, then freed on appeal in a landmark ruling that the evidence could not support the verdict. No one else was ever charged. The killing became one of the most analysed murder mysteries in British history, admired by crime writers as a case that seems to close every door at once. This file separates the documented crime from the still-open question of who committed it.

## The claim
That the murder of Julia Wallace is genuinely unsolvable: that the fake Qualtrough telephone call and the wild-goose errand to a non-existent address make the case a locked puzzle in which the husband could not have done it in the time available and no other identified suspect can be proven to have done it either, so guilt can be argued with equal force in every direction and never decided.

## Origin and timeline
- 1931-01-19: At about 7:15 p.m. a man telephones the Central Chess Club, which meets at the City Café in Liverpool, and leaves a message for William Herbert Wallace. The caller, giving the name R. M. Qualtrough, asks Wallace to call at 25 Menlove Gardens East the next evening at 7:30 to discuss an insurance matter. Club captain Samuel Beattie takes the message; Wallace, who has not yet arrived, is given it when he gets there. The call is later traced to a public phone box a few hundred yards from Wallace's own home.
- 1931-01-20: In the early evening the Wallaces' milk boy, Alan Close, delivers to 29 Wolverton Street and sees Julia Wallace alive at the door. The exact minute of that sighting, somewhere around 6:30 to 6:45, becomes one of the most fiercely disputed facts in the case, because it fixes how little time Wallace could have had.
- 1931-01-20: Wallace sets out to keep the Qualtrough appointment, taking a series of trams toward the Menlove Avenue district. Asking directions repeatedly, he establishes that there are Menlove Gardens North, South, and West, but no Menlove Gardens East. He even checks with a policeman and a shopkeeper before giving up and heading home.
- 1931-01-20: Returning around 8:45, Wallace finds he cannot get in at the front or back door. With his neighbours, Mr and Mrs Johnston, present, he tries again and the back door opens. Inside, Julia lies dead in the front parlour, her head battered by repeated blows. A mackintosh raincoat belonging to Wallace is found partly beneath the body, singed as if it had been near the gas fire.
- 1931-01-21: Police examine the scene. A small sum, reported as around £4 of insurance collection money, is missing from a cash box, though a larger sum and other valuables are left untouched. An iron bar and a poker are said to be missing from the house and are never found; no murder weapon is recovered.
- 1931-02-02: Wallace is arrested and charged with the murder of his wife. The prosecution theory is that he invented Qualtrough himself, made the call from the box near his home before going to the club, and used the fruitless errand the next night to build an alibi for a killing he had already committed.
- 1931-04-22: Wallace's trial opens at the Liverpool Assizes before Mr Justice Wright. The evidence is entirely circumstantial: no weapon, no eyewitness, no blood found on Wallace, and a tight timetable that the defence argues leaves him no realistic window to kill, clean up, and depart. The judge's summing-up is widely read as favouring acquittal.
- 1931-04-25: After deliberating about an hour, the jury finds Wallace guilty. He is sentenced to death. The verdict startles many observers, given the thinness of the case and the judge's cautious summing-up.
- 1931-05-19: The Court of Criminal Appeal quashes the conviction, holding that the verdict “cannot be supported, having regard to the evidence.” Wallace walks free. It is the first time an English murder conviction is set aside on that ground under the Criminal Appeal Act 1907, and the ruling, reported as R v Wallace, becomes a landmark.
- 1933-02-26: Shunned by some former customers and worn down by the ordeal, Wallace dies of kidney disease at the age of 54, still protesting his innocence. No one is ever charged with Julia's murder, and the case remains officially unsolved.

## The evidence, claim by claim
- Claim: Julia Wallace was murdered in her own home on the evening of 20 January 1931.
  Evidence: This is settled and undisputed. She was found beaten to death in the front parlour of 29 Wolverton Street, her skull fractured by multiple heavy blows. The medical and scene evidence established a violent, deliberate killing. Everything contested in the case is about who struck those blows, not whether the murder occurred.
- Claim: The Qualtrough phone call proves Wallace set up his own alibi.
  Evidence: It proves no such thing, though the prosecution built its case on it. The call was real and was traced to a box near Wallace's home, which is consistent with him making it, but equally consistent with a killer who knew his movements choosing that box to point suspicion at him. Nobody who took or overheard the message could identify the voice as Wallace's, and the club captain Samuel Beattie, who spoke to the caller, did not think it sounded like him. The call is the pivot of the mystery precisely because it fits both stories.
- Claim: The timetable made it physically impossible for Wallace to be the killer.
  Evidence: This is the heart of the defence, and it is strong but not conclusive. If the milk boy Alan Close saw Julia alive as late as some accounts hold, Wallace would have had only minutes to commit a bloody murder, remove all trace from himself, dispose of a weapon, and catch his tram. Investigators and later analysts have argued over Close's exact timing for decades. The window is tight enough to make guilt hard to credit, but not so airtight that it has ever been proven impossible.
- Claim: There was no forensic trace linking Wallace to the killing.
  Evidence: Correct, and it weighed heavily on appeal. A beating that fractured Julia's skull would be expected to splash blood, yet none was found on Wallace, his clothing, or in a way that fit a hurried clean-up in the time available. The absence of physical evidence, combined with the circumstantial-only case, is what the Court of Criminal Appeal cited in ruling the verdict unsupportable.
- Claim: Robbery was the motive, which points away from the husband.
  Evidence: This is genuinely ambiguous. A small amount of insurance money was taken while larger sums and valuables were left, which some read as a burglary interrupted or staged, and others as a thin attempt by Wallace to fake a robbery. The scene supports a reading in which an outsider knew Wallace collected cash, called him away, and came for the money; it also supports a reading in which the theft was set dressing. The evidence does not decide between them.
- Claim: A specific other man, later named as Richard Gordon Parry, was the real killer.
  Evidence: This is the leading alternative theory but remains unproven. Parry, a young acquaintance who had done insurance-round work connected to Wallace, was investigated in 1931 and gave an alibi. In a 1981 radio documentary a garage attendant, John Parkes, said Parry had come to his garage on the murder night to clean the inside of his car and that a bloodstained glove was seen. It is a striking account, but it surfaced fifty years later, Parry was never charged, and no physical evidence ties him to the scene. It is a serious suspicion, not a solution.
- Claim: The appeal ruling means the courts declared Wallace innocent.
  Evidence: Not quite. Quashing a conviction because the evidence cannot support it is a finding that the Crown did not prove guilt to the required standard, not a positive declaration of innocence. In law Wallace was no longer a convicted man, and he is entitled to the presumption of innocence, but the ruling settled the legal question of his conviction, not the factual question of who killed Julia. That question the court did not answer, and no one since has answered it with proof.

## Why people believe it
- The case is built like a detective puzzle, which is exactly why it grips people. A fake name, a phantom address, a phone box near the suspect's home, a knife-edge timetable: it reads like fiction, and crime writers from Dorothy L. Sayers to Raymond Chandler analysed it as though it were a chess problem with a hidden solution.
- Both stories are genuinely coherent. You can lay out a persuasive account in which the mild, chess-playing husband is a cold planner who invented Qualtrough, and an equally persuasive account in which he is an innocent man framed by someone who studied his routine. When each theory explains the same facts, the mind keeps circling for the tie-breaker that never comes.
- The legal drama is unforgettable on its own. A man sentenced to hang on purely circumstantial evidence and then freed by a landmark appeal is a story about the justice system, not just a whodunit, and it gives the case a weight beyond the crime itself.
- It is genuinely unresolved. Unlike theories that persist against a clear answer, the Wallace case has no established solution to argue against, so the debate is not a refusal to accept the truth but an honest search for one that the evidence has never delivered.

## Open questions
- How accurate was the milk boy's timing? Alan Close's account of when he last saw Julia alive is the linchpin of the whole timetable, and small differences in that minute swing the case between plausible and impossible for Wallace. His recollection was pressed and revised, and it can no longer be tested.
- Who made the Qualtrough call, and in what voice? The call was traced to a box near Wallace's home but never to a speaker. Whether it was Wallace disguising himself or someone imitating an ordinary caller to frame him is the single fact that would break the case, and it was never established.
- Is the case against Richard Gordon Parry more than suggestive? The garage-attendant account named him decades on and remains uncorroborated by physical evidence. Whether Parry had the means and opportunity, and whether the late testimony can be trusted, is still argued and cannot now be resolved.
- Why was so little taken, and was the robbery real? The mix of a small stolen sum and untouched valuables fits both an interrupted outside burglary and a staged one, and the scene has never yielded a reading that forecloses either.
