Readers are loving GHOST OF WHITECHAPEL ***** - 'It had everything; suspense, murder, mystery and humour - a really good read.' ***** - 'Authentic, darkly comic in places, thoroughly enjoyable.' ***** - 'I was engrossed from beginning to end. The characters were so real and funny.' ********************************************************* When Bridget Cummings advertised for a lodger, she did not expect a policeman to apply for the room. She wasn't fond of the coppers, but her family allowed P.C. Fred Billings to move in and she seemed to have little say in the matter. Still, she was glad of his company in the walk back from her late-night washing up job, particularly when a young girl was found in a nearby street with her throat cut. The discovery of the body of Maureen Flanagan, a respectable woman, naturally stirred memories of Jack the Ripper. His horrific crimes had shocked the neighbourhood only twelve years before, although Chief Inspector Dobbs of the City of London Police believed that the Ripper was dead. But when a second body was discovered, and Bridget noticed a strange man following her, could the terror have returned?
