Doctor Wheasel’s Rotherfield investigations have come up trumps at the B.V.C. motorcycle works, where boss Gerry Thompkins has been fusing advanced alien metal with his bikes. The homicidal cycles are a risk that the good Doctor is not prepared to tolerate, but if he’s to do anything about it, he needs to escape from Tompkins’ gun sights, in the final part of this 1970s ENTITY adventure.
