When Laurie R King brought Sherlock Holmes out of retirement in The Beekeeper's Apprentice, readers were delighted. When she gave him Mary Russell, an American half his age, as a partner and wife, mystery fans around the world were astonished. Laurie R King had skilfully revived literature's most fascinating and eccentric snoop. Sherlock Holmes has received a call for help from an old friend. The Reverend Barring-Gould, noted parson and folklorist, wants Holmes to investigate some strange sightings. When Mary Russell realizes where their search will take them, however, her blood runs cold. A ghostly coach and giant dog have been glimpsed on Dartmoor-the chilling landscape of the Hound of the Baskervilles. As Holmes and Russell work through a challenging tangle of evidence, gossip, and legend to uncover the truth, the grey mystery of the moor swirls around them.
