‘"When Rogues Fall Out” incorporates some wonderful conundrums to hoodwink and hinder the cleverest of crime readers. This book contains three interconnected stories. In the first, a respectable collector of antiques falls victim to temptation. In the second a police inspector is found dead in suspicious circumstances in a railway tunnel. This section includes an interesting „essay” on the early use of fingerprint evidence. The third is a classic locked room mystery where someone has been making use of a sealed room in a remote country house. All three are resolved together in the last few pages. The rogues of the title include three very different men engaged in stealing and fencing high-quality jewelry. One is a working-class robber; one a refined antiques dealer turned fence; and one a mysterious middleman with the appearance of a gentleman.
