The Seventh Guest

Bernard Loxley promised his guests a new will by morning. Instead, they found him dead—poisoned behind a bolted door no one could have entered. Stranded by floodwaters at the sprawling Fenmore Hall estate, amateur detective Clive Rutherford confronts a household seething with old betrayals: blackmail, stolen patents, secret affairs, and a guest list altered by a single erased name. Six suspects remain. But the real danger may lie with the seventh guest—the one nobody expected.
