Here is another collection of the strange adventures of Doctor Morelle. The sardonic detective's cases include: an hotelier killed with a brass candlestick; a Baroness poisoned with cyanide; a diamond robbery, and the shooting of zoologist Professor Raymond. The doctor, in his inimitable cerebral style, also investigates: a fake suicide; the stabbing of the wealthy Mr Franklyn; the ex-prisoner accused of murder, and the strangled film star. All whilst aided - or handicapped - by his gentle, timorous assistant, Miss Frayle.
