Nightmare in Pink (Travis McGee Series, Book #2)

Nightmare in Pink (Travis McGee Series, Book #2) by John D. MacDonald

Travis McGee's permanent address is the Busted Flush, Slip F-18, Bahia Mar, Lauderdale, and there isn't a hell of a lot that compels him to leave it. Except maybe a call from an old army buddy who needs a favor. If it weren't for him, McGee might not be alive. For that kind of friend, Travis McGee will travel almost anywhere, even New York City. Especially when there's a damsel in distress.

The damsel in question is his old friend's kid sister, whose fiance has just been murdered in what authorities claim was a standard Manhattan mugging. But Nina knows better. Her soon-to-be husband had been digging around, finding scum and scandal at his real estate firm. And this scum will go to any lengths to make sure their secrets don't get out.

Travis is determined to get to the bottom of things, but just as he's closing in on the truth, he's knocked out and taken captive. If he's locked up in a mental institution with a steady stream of drugs being siphoned into his body, how can Travis keep his promise to his old friend? More importantly, how can he get himself out alive?
