All Through The Night

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.
