But the patient died

When Geoffrey Tremaine arrived at famed St. Justin's Hospital to confirm his new appointment as surgical registrar he found Everard Nicholson, the senior administrator, crumpled on the floor of his office in a coma. An emergency operation removed a brain tumor and Mr. Nicholson seemed well on his way to recovery when, suddenly and mysteriously, he died.

Tremaine quickly came to know the intimate and mysterious nature of his new hospital and his new colleagues and discovered that there was a horrible fear hanging over them all - a fear that had been set in motion by the late, and very dead, Mr. Nicholson.
