This week we find the crew of the Enterprise waiting to rendezvous with another Federation ship that's 3 days out. While they wait Data and Geordi decide to have an adventure on the holodeck as Sherlock Holmes and Dr. Watson, respectively. At first the adventure is short lived, but with a push from Dr. Pulaski the computer creates a foe that even Data cannot defeat. Will Data smoke a pipe while Geordi hangs on his every word? Will Pulaski be saved from tea and crumpets? Will the Captain out wit Professor Moriarty and will we find out that Geordi is an excellent craftsman? All these questions and more will be answered on this episode of Hailing Frequencies Open.
