London, 1895. Former Baker Street Irregular Timothy Badger and his partner in detection Benjamin Watson are in a spin: the eminent Dr John H. Watson has been kidnapped! The physician was enjoying a glass of sherry at his Baker Street residence before being bundled away in a barouche coach wearing only one slipper. Did Dr Watson know his captor, and where is he now? Could the mysterious ransom notes arriving in the post hold the answer?

With their mentor Sherlock Holmes out of the country, recovering the missing doctor could well be the biggest case the intrepid duo is ever likely to face . . . and if they don’t do so quickly, it could be their last!
