Sherlock Holmes is not at home this evening. Neither is his friend and colleague Dr. Watson.
Mr Holmes is rarely home unless knee-deep in a case (and unavailable anyway) or otherwise desperately waiting for a good one to come along. But on this particular evening, whatever the 'case', he is elsewhere.
Four ladies, all with strong ties to the Great Detective, one after another, are drawn towards and into 221b Baker Street in the hope of finding him at home.
