The Case of the Lazy Lover — Erle Stanley Gardner

MURDER WITH COMPLICATIONS
When Perry Mason receives two mysterious checks from Lola Allred, a woman he's never heard of, he smells trouble. A visit from Lola's husband reveals that she has run away with her daughter's boyfriend -- a key witness in an ongoing lawsuit.

The mystery deepens when the bank finds that one of the checks is forged. Yet when homicide finally does rear its head, even the unexpected victim isn't as surprised as Perry Mason.
