Diehl William. Sharky's Machine

Ballantine Books, 1995. — 479 p.Italy, 1944: A squad of American soldiers on a dangerous secret mission is ambushed and slaughtered... and a fortune in gold vanishes.
Hong Kong, 1959: An aging American colonel, haunted by his wartime past, is brutally murdered in a luxurious brothel.
Atlanta, 1975: The last survivor of the fatal World War II ambush in Italy is executed at point blank range in a parking lot.
Blowing away a crazed, gun-wielding drug dealer on a crowded city bus gets police detective Sharky bounced from the narc squad into the dreaded dregs of the department-vice. That's where he stumbles on a high-priced call girl and her pimp who are fleecing rich johns in an even higher-priced blackmail scam. Together with his "machine" of hard-bitten vice squad veterans, Sharky closes in for a big sting. He doesn't count on falling for Domino, his alluring target. Or falling into the middle of the murderous design she's a part of-involving a hot presidential candidate, the shadowy multimillionaire who's backing him, and the ice-cold assassin they're using to wipe out the past...before it blows their future to hell.
