Markham (Black Orchid)
From Tardis Wiki, the free Doctor Who reference
Sergeant Markham was a police officer in Georgian Oxfordshire. He was under the command of Sir Robert Muir. After Muir arrested the Doctor on suspicion of murder, Markham was ordered to convey the Doctor to the station. Before the arrest was finalized, however, the Doctor exonerated himself by allowing Muir, Markham and Cummings to enter his TARDIS. (DW: Black Orchid)
