HOMELESS IN HEAVEN by Connie Shelton (Heist Ladies Mysteries, Book 4‪)‬

Who would dare steal from homeless people, especially at Christmas! Mary Holbrook and Sandy Warner are volunteering at Heaven Sent, a homeless shelter, and discover it has been the scene of some thefts. The Heist Ladies decide to investigate.

 At the same time there are some strange doings at the New Age establishment next door. The Temple of the Rising Moon is run by gurus Orion and Sunshine, a husband and wife team living in a converted school bus, who claim to be raising money to build homes for poor people. As the Ladies dig deeper, they discover the charity is suspect and the hippies aren't exactly who they claim to be either.

  In their usual fashion, the dauntless Heist Ladies set out to track the money and chase down the perps. All in the name of justice!
