Description:

Mitch McDeere has worked hard to get where he is: third in his class at Harvard Law. Aggressively recruited by all the top firms, and initially headed for Wall Street, Mitch surprises everyone by joining Bendini, Lambert & Locke, a very private, very rich tax firm in Memphis. Mitch and his wife, Abby, move to Tennessee and quickly settle into their new life: they’re young, happy, and on the fast track. Or so they think.

Soon, though, Mitch senses trouble: two of the partners die in a suspicious diving accident off Grand Cayman; the firm’s management is overly proud of the fact that no one has ever resigned; and security measures at the firm, even for a company with billionaire clients, are more than a little stringent. Then, suddenly, Mitch’s vague suspicions come to life.

The FBI has the lowdown on Mitch’s firm and needs his help. Now Mitch is caught between a rock and a hard place. The FBI will bust him if he doesn’t cooperate, and the firm will kill him if he does. There’s no way out.

Or is there?
