In the early hours of Wednesday, 11 February, a 43-year-old prostitute named Margaret Florence Lowe was murdered in her flat at 11 Gosfield Street, Marylebone. She was last seen alive by a neighbour named Florence Bartolini at approximately 1:15 a.m. walking along the corridor to her flat in the company of a client. Bartolini later heard the man exit Lowe's flat, walk down the corridor and onto Gosfield Street, whistling to himself. Lowe's body remained undiscovered until the afternoon of 13 February, when her 15-year-old daughter, Barbara, visited her mother only to be told by a neighbour her mother had not been seen for "two or three days" and that a parcel had remained unclaimed outside her door for the same length of time.
