Frances Baird is a detective with the Watkins Agency of New York City. She and a colleague are sent undercover to "The Maples" to guard a valuable set of diamonds during the festivities leading up to the marriage of Mr. Deneen's eldest son, James Jr. Within a few hours of their arrival, however, this seemingly simple task turns into something much more sinister, and it is ultimately left to Frances to unravel the truth of the matter.

From the dedication: "On a train by day, or abed by night, you will read "Money to Burn" and immediately forget it--which is as it should be, for then you can profitably reread it a year hence--but I'm certain it will entertain you while you are reading it. If it gives you the realization of good fights on strange islands in tropic seas, if it stirs you with the sense of its hairbreadth escapes, if its mystery "keeps you guessing" and inveigles you past your proper railroad station, or runs up the house electric light bill by holding you tight until morning, then it is the sort of book that I have planned it to be..." - Summary by Steven Seitel
