RADIANT ANGEL, by Nelson DeMille
Corey, whose short fuse is legendary as well as the despair of his FBI wife, tracks
When Russian colonel Vasily Petrov of the Russian Foreign Intelligence Service and a dozen beautiful escorts walk down the beach and disappear from view at the height of a party Corey has infiltrated, alarms go off in the detective's head but nobody else is disturbed. Rejecting the conservative approach of asking his superiors for direction, Corey and a reluctant counterpart with mysterious connections follow the fast-vanishing trail.
If you enjoy edge-of-the-seat, high body count tales, DeMille is the author for you, and John Corey is the character, in every sense of the word. Confrontational, confident, smart-ass Corey will keep you entertained as well as terrified.
It's a 5. The series is best read in order as there's quite a bit of carry-over.
