Derrick in particular had been convicted of rape but was pardoned by the Earl of Essex (clearing him of the death penalty) on the condition that he became an executioner at Tyburn.
Derrick, în special, a fost condamnat pentru viol, dar a fost iertat de contele de Essex (care l-a iertat de pedeapsa cu moartea), cu condiția ca el să devină un călău la Tyburn.
