The Mephisto Club by Tess Gerritsen (2006, Hardcover, Large Print)

Tess Gerritson has again proven herself a master of medical suspense. She's been on an accelerating crescendo and with THE MEPHISTO CLUB she has hit the pinnacle. Her dynamic duo protagonists, Maura Isles and Jane Rizzoli, plunge themselves into demonic territory at a relentless pace as Gerritson creates exacting detail and shockingly realistic medical-police interactions. Gerritson is the master, but for fans of this genre, there's a new physician-author, Patricia Gussin, who wrote SHADOW OF DEATH, another example of fast paced suspense laced with authoritative medical detail - if that's what you like.
