Around bleak Dartmoor, where the Hound from the Baskervilles once bayed, three children have been brutally murdered. Today Richard Jury of Scotland Backyard joins forces with a hot-tempered regional constable called Brian Macalvie to track down the killer. The trail starts at a desolate pub, Help the indegent Struggler. It qualified prospects right to the property of Woman Jessica, a ten-year-old orphaned heiress who lives with her secret uncle and ever-changing group of governesses. And as suspense spreads over the forbidding landscape, a vintage injustice comes back to haunt Macalvie…with hints that link a murder in the distant past having a killing however to come.
