Toper's End

Toper's End is a 1942 detective novel by the British authors G.D.H. Cole and Margaret Cole. It was the final entry in their series of over twenty books dating back to 1923 featuring Superintendent Wilson, a former officer of Scotland Yard turned Private Detective. Part of the Golden [Age of Detective Fiction], it takes place against the backdrop of the Second World War. It was published by the Collins Crime Club.
Ralph Partridge wrote in The New Statesman "The caricatures of refugee mentality are still amusing, but the plot is hackneyed and the detection, in spite of a great ox of a clue staring everyone in the face on an early page, is so feeble that Superintendent Wilson actually has to use third degree methods to extort a confession." Maurice Richardson wrote a more appreciative review in The Observer.
