The philosophical Detective Adjutant Grijpstra and his assistant, Sergeant de Gier, appear in eight of these superb mystery stories. In one they learn which of two lady friends put a bullet through the head of a handsome oceanographer found dead amidst his tanks of shiny, living mussels. In another they strong-arm a brutal crime-lord whose henchman threatens the sergeant's cat. Another finds them wondering how a man could explode a wife-killing bomb in the country while he was, all the time, in his city office. Still another leads them to a murderer whose weapon is a chocolate Easter bunny. And that's just the beginning: the collection contains six other stories, each touched with that curious blend of wit and the macabre which readers have come to expect from the pen of Janwillem van de Wetering. There goes Ravelaar—Six this, six that—The deadly egg—Sure blue, and dead too—The sergeant's cat—The machine gun and the mannequin—Houseful of mussels—Letter present—A tasty tidbit—A great sight—A tale with an end—Jacob Sander's final solution—The yoga yo-yo—The new disciple
