The Haunted Manor: A 1920s Historical Mystery

by Cassie Rush

A crumbling mansion. A rising tide. And a body on the staircase.Bundle Ridgewell has a keen mind, a dry wit, and a husband whose enthusiasm for dubious business ventures keeps landing them in trouble. This time, it's a weekend at Redwood Keep — a Gothic mansion surrounded by marshland and accessible only at low tide.

But when the host's private secretary is found dead on the grand staircase, Bundle suspects something far darker than an accident. Trapped with a houseful of suspects and a killer who isn't finished, she and Binky must untangle stolen identities, occult rituals, and long-buried family secrets before the next victim falls.
