Summary: a Peter Duluth mystery...
Review: the Playgel mansion was an insane Shangri-la with a spectacular view of Lake Tahoe. The guest list included cowboy casino owner, a voluptuous blonde man-eater, a countess, the wife of a distinguished heart specialist, and of course, Peter Duluth and his movie actress wife, Iris. Then their fabulously rich and wanton hostess, Lorraine Pleygel, had an absolutely splendid idea...since three of her house guests were in Reno to get divorced, why not invite the discarded spouses for a reconciliation? A poisoning, a drowning, and a bash in the head later, Peter and Iris found themselves searching for a killer who took "till death us do part" rather literally.
