Deadly Quicksilver Lies is a fantasy novel by American writer Glen Cook, the seventh novel in his ongoing Garrett P.I.

[1] Garrett is a hardboiled detective living in the city of TunFaire, a melting pot of different races, cultures, religions, and species.

With Dean out of town, the Dead Man asleep, and only the Goddamn Parrot for company, Garrett finds himself wishing for something new.

As word of a long buried treasure gets out, even more parties climb into the fray, leaving Garrett bruised and battered again.

In a typical novel-ending plot twist, Grange Cleaver dies, things settle down, and Garrett is left to mull over the possibilities.
