Norb Vonnegut is the seriously underappreciated author of three glittery thrillers about fiscal malfeasance. This may not sound like a red-hot franchise, but he has made it one. With “Top Producer” (2009), “The Gods of Greenwich” (2011) and now “The Trust,” he is three for three in his own improbably sexy genre.

Mr. Vonnegut dreams up diabolically elegant business crimes, then sends smart-talking characters to follow the money.He draws upon his own Wall Street experience (with Morgan Stanley, among other employers) to provide the sound of insider acumen. “I’ve had 14 managers over the last 10 years,” Grove O’Rourke says at the start of the new book. Grove was the stockbroker hero of “Top Producer,” and now he’s back for an encore.

“I’d call them an endangered species,” he says about his string of callous, browbeating bosses, “except the supply is endless.”
