Simon Schuster, 1998, 170 pages Mary Higgins Clark, the Queen of Suspense, celebrates the season with this Christmas classic featuring two of her most beloved characters. All of Alvirah's deductive powers and Willy's world-class common sense are called upon as the two stumble into a Christmas mystery. A woman abandons her newborn at a Manhattan church. Simultaneously, a thief is absconding with a treasured artifact, a chalice adorned with a star-shaped diamond. To elude police, he grabs the stroller and disappears. Seven years later, the mother returns to the scene and finds Alvirah and Willy helping neighborhood kids prepare for a Christmas pageant at an after-school shelter. Soon the savvy sleuths set out to solve the puzzle of the missing child and chalice -- and to unmask scam artists threatening to shut down the shelter.
