This is one of the most memorable episodes in this very tidy true crime series from the 1950s with the emphasis on truth rather than fiction, introduced by the ever-sepulchral criminologist, Edgar Lustgarten. It is from the outset grisly - the discovery of a dismembered leg in a canal.Very neat character vignettes which advance and add interest to the plot from a master-tattooist, a man with a missing wife - and Albert Steptoe (Wilfred Brambell) as a pathologist.

Only one limb was found in the canal so the search resumed. Lustgarten intoned: "The police continued their legwork" I'm sure he didn't intend the pun, he very much left it to others to do any humour in this series.

Another worthy series choice by Talking Pictures TV 6.5 out of 10
