Blood from a Stone: A Jack Haldean Mystery

The village folks (circa 1926) are shaken when widowed Mrs. Paxton is poisoned in her home. It's believed that her nephew killed her for her sapphire necklace, and now he's disappeared. Turns out the jewels had been willed to Evangeline Leigh, who is Celia Leigh's stepmother. Series regular Isabelle Thornton is Celia's friend. A few weeks later, a passenger is murdered on the same train on which Isabelle is riding; puzzlingly, a sapphire necklace is found at his feet. Isabelle remembers the Paxton connection, and soon Scotland Yard Insp. Bill Rackham asks his buddy Jack Haldean to investigate. Jack and Isabelle begin snooping around the Leigh family estate. On the grounds are some noteworthy British Roman ruins, including an underground altar, and Jack and Isabelle make some shocking discoveries. Problem is, another guest knows more, and things get excitingly dangerous.
