"D" Is For Deadbeat by Sue Grafton

Kinsey Millhone, private investigator, gets into an emotional tangle this time. A man who identifies himself as Alvin Limardo hires Kinsey to find Tony Gahan, recipient of a $ 25,000 cashiers check. Alvin, of questionable character, ends up dead and Kinsey,left with a bounced check for $ 400.00, feels obligated to find out what was going on. Kinsey is as stubborn and eccentric as ever. A good read, somewhat down at the end.
