I adore these books, though some are better than others, of course.
This anthology contains novels #4 through #6 in the Garrett, P.I. series.

In Novel #4, someone—or something—is murdering the employees of retired General Stantor. Now, this growing legion of the dead wants to add the general to their ranks. And it's up to Garrett and the half-elf Morley Dotes to protect Stantor and find the killer.

In Novel #5, somebody had lost a lot of brass, and everyone wants to find it. And now the stakes were getting so rich it makes even a hard-boiled detective like Garrett nervous.

In Novel #6, Garrett reluctantly takes on a serial killer psycho who does too good a carving job and never leaves any of the blood behind.
