A Case of Accidental Intersection, by W. S. Gager
Mitch Malone hates hospitals, but when a suspicious traffic accident lands a comatose victim in the hospital, he must put that aside to find the truth. The surface looks smooth but the more the crime beat reporter looks the more bodies pop up, including a private detective and his own editor. Can he get to the truth before the surviving victim is murdered in her hospital bed and an elderly witness has a heart attack? Will he get his exclusive printed before he's the next victim?
