Carrington Rexton is a bit nervous. His son Richard has just returned from medical studies in Europe and there's a house party going on to hail the conquering hero...so to speak. So, what's making Papa Rexton nervous? Well...he doesn't quite get these young folks and there's a fellow that Richard has brought back with him who seems a bit suspicious. And...oh yeah...Rexton has a bunch of sparkly emeralds and a rare necklace that aren't exactly as secure as they ought to be.
Rexton arranges (through District Attorney Markham) to have his old friend Philo Vance on the premises to look everything (and everybody) over and see if his fears are groundless. Vance meets the guests and inhabitants of the Rexton manor--from son of the house and the invalid daughter Joan to Ella Gunther, companion to Joan and a secret ice skating star; from Carlotta Naesmith, society girl and Richard's intended--at least intended by Papa Rexton--to Stanley Sydes, man about town and avid treasure-hunter.
S. S. Van Dine is the pseudonym used by American art critic Willard Huntington Wright (October 15, 1888 – April 11, 1939) when he wrote detective novels. Wright was an important figure in avant-garde cultural circles in pre-WWI New York, and under the pseudonym (which he originally used to conceal his identity) he created the once immensely popular fictional detective Philo Vance, a sleuth and aesthete who first appeared in books in the 1920s, then in movies and on the radio.
