Desperate Remedy

Description for DESPERATE REMEDY by Mary Kittredge:

Something is desperately wrong at Chelsea Memorial Hospital. Resident physician Victor Clarke has been shot down in the street only hours before his wife is murdered in their home. The doctor's private nurse is strangled and his respirator is turned off in yet another attempt. When the murderous acts come to light, the public relations nightmare proves too much for hospital administrator Ned Hunt to handle without his childhood friend Edwina Crusoe, the hospital's nurse turned medical investigator. Edwina must step in to save the hospital--and Ned's career--even though she's three months pregnant and more than a little queasy. While Edwina tries to remain serene, she must track a merciless killer without a single clue--before he succeeds in silencing Dr. Victor Clarke permanently.

This is #5 in An Edwina Crusoe Medical Mystery.
