Michelle Birkby has always loved crime stories, and read her first Sherlock Holmes book when she was thirteen. She was given a beautiful collection of all the short stories and has been hooked with the wonderful, gas-lit, atmospheric world of crime and adventure ever since. A few years ago Michelle was re-reading The Empty House and a blurred figure in the background suddenly came into focus. It became clear to her that Mrs Hudson was much more than a housekeeper to 221b and she'd always been fascinated by Mary Watson's character. So she set about giving the women of Baker Street a voice and adventures of their own . . . The House at Baker Street is the first book in the exciting Mrs Hudson and Mary Watson Investigations.
