Stand Up and Die — Richard Lockridge

A Handsome young Marine met a beautiful girl and an invalid grandmother with an income tax in the upper brackets. Naturally, there was a doctor prescribing for grandma, a lawyer ministering to the needs of mammon, and shortly, Captain heimrich of the State Police investigating murder. The young Marine did not get the situation well in hand. Grandma forgot her script and stood up to die. Whodunit?...You'll be surprised.
