Dr. Thorndyke is the CSI of his day. Most of the book is taken up with the account of how an innocent man gets himself thoroughly entangled in what looks like the certainty that he will be hanged, either for the death of a man he saw only once, or amazingly, for his own death! But, of course, Dr. Thorndyke is able to extricate him from this awful situation and triumph yet again. This is the amazing story of a polite, artistic gentleman who, by a series of mistakes, accidents, bad decisions and bad luck finds himself accused of two murders and a fraud. One of the murder victims is himself! No one but Dr. Thorndyke could possible clear up the confusion.
