The god of the hive : a novel of suspense featuring Mary Russell and Sherlock Holmes by Laurie R. King

The God of the Hive picks up where The Language of Bees abruptly left off.  Mary Russell and Sherlock are on the run.  Mary has Sherlock's little granddaughter in tow and is trying to fly back to London in one piece. Sherlock has abducted a doctor to care for his severely wounded son while they attempt a boat crossing to Holland. Both believe they are being followed by the cult leader responsible for the ritualistic murder of Sherlock's daughter-in-law and others. What they have yet to discover is that the cult leader was only a pawn in a Secret Services power struggle.  King introduces the unforgettable character of Robin Goodfellow-shell shocked veteran, childlike woodsman, and implacable protector of the helpless.  An amazing adventure read! 354 pages.
