Sherlock Holmes has exposed the dreadful secret of the House of Silk. But still it isn't clear what links the house of ill repute to the destruction of the paintings by the Flat Cap Gang in Boston and the murder of the man in the flat cap at the hotel in Bermondsey. And so he returns to where the case began, at the home of the art dealer, Edmund Carstairs, in Wimbledon.
