• Constable Luke
• Played by Wayne Forester

Fresh from his triumph of failing utterly to solve the murder of Gordon Way in the first Dirk Gently series, Constable Luke returns to demonstrate that a one-watt brain can power an adult-sized human body. The despair of the Metropolitan Police but in his own mind a razor sharp force of law and order, Constable Luke is ordered to keep an eye on Dirk Gently but finds himself under the spell of the forces of evil in the new series.
