Bullitt - Robert L. Pike

'Rossi isn't dead yet. And from what I hear, the Rossi brothers are pretty tough monkeys.' Clancy's knuckles whitened on the steering wheel. 'Yeah,' he said. 'They're all tough monkeys. Until they lose those precious ten pints…'

Lieutenant Clancy, a tough cop from New York's 52nd Precinct, has been handpicked for an assignment. Assistant District Attorney Chalmers needs him to protect a witness whose testimony is vital. That man is Johnny Rossi, an infamous gangster involved in every West Coast racket from prostitution to gambling, who has turned into a whistle-blower. Shacked up in a fleabag hotel, Rossi should be safe. But when a hood with a shotgun breaks past the police guard and blasts Rossi into a critical condition, Clancy has just seventy-two hours to find out why Chalmers can't keep his mouth shut about his so-called secret case, why Rossi came to New York in the first place, who else knows where he is and when they are coming to finish the job off.
