The Van Renn Legacy — Julie Kistler

The rules were strict: no press and no professionals

But what about partners? Daisy wondered. For it seemed that, rules or no rules, Peter Devlin had signed on for the duration of the madcap hunt for Cornelius Van Renn's legacy. Daisy's feelings were mixed. The suave, renegade Mr. Devlin had a knack with Grandfather's sphinx-like clues, and their wild dash through Long Island and Manhattan was taking them ever closer to the mysterious treasure. Yet Daisy repeatedly found herself entangled in barely legal, shockingly risque situations that Peter, quite suspiciously, seemed to find amusing. Grandfather would never have approved of Daisy's partner; Daisy wasn't even sure she did!
