I am going to commit a murder. I offer no apology for the curtness of the statement. An individual taking the name 'Marius' boasts in a series of letters that he will commit the Perfect Murder, daring Scotland Yard detectives to catch him if they can. Ex-CID officer John Franklin and the amateur but astute detective Ludovic Travers will need to draw conclusons from a soiled letter, a locked room murder, four cast-iron alibis, and trips to France, in a feverish search for the killer and proof of his misdeeds-before 'Marius' can strike again. The Perfect Murder Case was originally published in 1929. This new edition
