Jasper Jeake
From Tardis Wiki, the free Doctor Who reference
Jasper Jeake was a frequent patron of the Diabola Club, often visiting with his friends Edmund Carteret and Quincy Flowers. He rescued Turlough after accidentally hitting him with his carriage, and later helped the Fifth Doctor investigate the mysterious disappearances around London, eventually tracing them to Sir Nikolas Valentine.
