Mycroft has a missing agent; the stepdaughter of Lord Wexford Foyle wants a pearl brooch authenticated. Sherlock Holmes has little interest in either until he learns the gem is the Jacobite Rose, a royal treasure. Reading Debretts Peerage, Holmes discovers Lord Foyle has a brother who is known as a craftsman in gold. Three strange clues the drawing of a rose, fish scales and a fragment of pine resin discovered at the last known locus of the missing man begin to link the two cases. This two act play, with ten main characters, is laid out in a large format ideal for theatre groups and classrooms.
