BAD BLOOD

They were barroom pals who talked about politics, philosophy, everything but their private lives ... until the night Tom Crandall asked detective John Marshall Tanner for help. It seems that Tom's sultry wife, Clarissa, was having an affair with Richard Sands, a ruthless corporate raider with enough money, guts, and power to get whatever he wanted.

But did Richard Sands want Tom Crandall dead? That's the question confronting Tanner when his friend's lifeless body is found in an abandoned alley in San Francisco's sleazy Tenderloin district. The cops are calling it suicide, but Tanner doesn't buy it, because the last message Tom left on his answering machine hinted at something that went far beyond a marriage gone wrong. Now Tanner resolves to trace Tom's last steps... only to find that the clues lead to Tom's brother -- a raving schizophrenic whose wild accusations of a chilling conspiracy may not be so wild after all.
