Thirteen Diamonds (Lillian Morgan)

Lillian Morgan is bored with life in a retirement community, but she gets more excitement than she hoped for when a fellow resident drops dead at the bridge table--while holding a perfect hand of thirteen diamonds. Intrigued by the astronomical odds against this happening, she uses her mathematical background plus assistance from her beautiful granddaughter and friends to prove that a murder was committed--but not everybody wants her to find the murderer. br /
