Quality Murders

In a hospital, young residents are the princes of night. It's their magic kingdom, full of terrors, tall stories, and urban legends. But night is always a wild card, and now at College Hospital in Manhattan, nights have turned from magic to horror. One patient after another is being murdered. Strange nurses seem to be involved, but whoever is doing this, Amir Baum, brand new intern, is getting blamed for having a "fund of knowledge deficit." His girlfriend Grace Paine, statistician and more than eccentric, is on the case to clear his name, but the killings also seem to involve a nearby hospital chain. Why are the sickest patients dying at one place and the least sick at another? How are the fatal complications being chosen? And what is College Hospital's aging computer guru Evelyn Pearson, the disappointed romantic, up to?
