A good early locked room mystery, written in a very humorous, satirical style. On a foggy day in the Big Bow District of London, Mrs. Drabdump becomes fearful for her lodger. She knocks several times at his door but no answer. She runs to Inspector Grodman and together they break down his door to find the pooor man lying in his bed with his throat cut. The door was locked from the inside. Thus begins Israel Zangwill's classic mystery.
