Now in paperback—the national bestselling series continues with Helen Hawthorne going undercover in a library to solve a murder and recover a painting.

Wealthy socialite Elizabeth Cateman Kingsley has hired Helen to find a missing John Singer Sargent painting, owned by her late father. After his death, many of Davis Kingsley’s books were donated to the Flora Park Library, and his daughter suspects the small watercolor—worth a million dollars—was tucked away inside one of those dusty tomes.

Helen applies for a job as a library volunteer and discovers the library has a catalog of complaints—from a mischievous calico cat to the mysterious disappearance of various items that some are attributing to a ghost. Soon a dead body turns up in a parking lot. Now Helen must find the killer as well as the painting—before she’s taken out of circulation herself.
