Life Support is the 10th stand-alone novel by Tess Gerritsen. Springer Hospitals night-shift ER doctor, Toby Harper, finds her job is on the line when she literally loses a patient. The elderly man presents with confusion and apparent seizures, but while the ER staff are dealing with another emergency, the patient disappears. When another patient with identical symptoms, from the same exclusive residential community, with the same doctor, dies in the hospital, Toby wants to investigate further, fearing an infectious cause. As Toby tries to find out more, she hits a brick wall with the admitting doctor and the residential community, which arouses her suspicions. But problems in her personal life complicate matters even further. Medical murder mystery is Tess Gerristens forte and she, once again, gives us a great plot and credible characters and dialogue. The ME in this novel can, in some ways, be seen as the blueprint for Maura Isles role in the Rizzoli and Isles series. Another great Gerritsen read.
