This is book 32 of the "Spenser" series.

This note contains spoilers for the book.

So this time it's Hawk that gets shot (three times from behind with a high-powered rifle), and Spenser who has to nurse him back to health and help him get revenge.

Hawk was working as a bodyguard at the time, and they got the guy he was protecting, and his family except for one. So part of his reparations (mostly to his own honor) is to get 5 million dollars out of one of the bad guys to start a trust fund for the kid. But Hawk doesn't get sloppy about it. I mean. Hawk.
