The Invisible Hand: A Pareto Sisters Mystery (Paperback) (ISBN-13: 9781970157390)

An unseen nighttime threat is terrorizing the neighborhood dogs. Cell phones aren't working. Valuable jewelry is disappearing from homes. Fenton Pareto, a mysterious private investigator, enlists his daughters, eleven-year-old Charlie, and fifteen-year-old Clarke, to help piece together the puzzle.

The Pareto sisters discover the perpetrator is orchestrating these events from far away. This same dark adversary has pinned a crime on the girls. To discover the truth, the sisters must overcome dangerous mechanical insects, high-voltage booby traps, weaponized music, and malicious QR codes before time runs out.

Get ready for a wild ride through an affluent San Francisco Bay Area enclave inhabited by eccentrics, pampered dogs, intrusive parents, and donut lovers.

P.E. Klein lives in Menlo Park, California. He has two exceptional daughters who should not be compared to the quirky and flawed characters in his novel. The Invisible Hand is the first installment of a three-book series featuring the Pareto sisters.
