The Impossible Murder of Julia Wallace

In 1931 Liverpool, a mysterious phone call about a business opportunity sent William Herbert Wallace to a non-existent address. He returned home to find his wife, Julia, murdered inside their locked house. With no forced entry and a timeline that baffled investigators, police zeroed in on William, believing the call was a fabricated alibi. He was convicted of murder, but in a stunning reversal, the verdict was overturned, leaving the case unsolved. This is the story of one of Britain’s most enduring and debated locked-room mysteries, a puzzle that continues to fascinate armchair detectives nearly a century later.
