Slight Mourning

Twelve people sat down to dinner at Strontfield Park, William Fent's ancestral home. But by midnight the host was dead - killed in a car crash as he was giving one of his guests a lift home. The problem for Detective Inspector CD. Sloan was the autopsy. For the victim - apparently - would have died anyway. Along with the cold cucumber soup, crown of lamb, raspberry crémets, and a fine old port, someone had slipped the lord of the manor a dose of deadly poison. But which of the surviving eleven had the opportunity... and why
had anyone wanted him dead?
