Code Blue — Janet Lane Walters

In the medical mystery Code Blue nurse Susan finds the body of the hospital's “gossip queen” in the orthopedic storage room. She doesn't realize this is the first of a series of murders involving her colleagues or that her life is in danger. She is a widow and is exploring a new romantic relationship that promises love but she fears the man she is falling for is as controlling as her dead husband. The arrival of courtship gifts, at first, seen as innocuous soon takes on a sinister note.
