What happens to a priggish, WASPy, disillusioned Wall Street lawyer when a Mafia crime boss moves into the mansion next door in his posh Long Island neighborhood? He ends up representing the gangster on a murder rap and even perjures himself so the mafiosostet lc can be released on $5 million bail. That's the premise of DeMille's (The Charm School) bloated, unpersuasive thriller. Attorney John Sutter has problems that would daunt even Fitzgerald's Jay Gatsby. His marriage is crumbling, despite kinky sex games with his self-centered wife, Susan, who's the mistress of his underworld client Frank Bellarosa. The IRS is after Sutter, and his law firm wants to dump him. As a sardonic morality tale of one man's self-willed disintegration, the impact is flattened by its elitist narrator's patrician tones. A comic courtroom scene and some punches at the end, however, redeem the novel somewhat
