Dartmoor
Dartmoor was a prison in the English county of Devon, as depicted in Sherlock Holmes Program 3A.

In 2365, Data, in the guise of Sherlock Holmes, deduced that a man found murdered in the street had been released from Dartmoor that day. He based this conclusion on the shoes the man was wearing. ()
