 At this point Dangerfield, who has befriended Mrs Sturk, decides to try to ensure Sturk's death (and perpetual silence) by having him trepanned, which he has been assured by medical experts is guaranteed to kill him.However, he is unfortunate enough to secure the services of "Black Dillon", a debt-ridden, alcoholic doctor from Dublin who is, however, an unusually capable surgeon.When Dillon is several hours late for the appointment at Sturk's house, Dangerfield gives up and leaves, but Dillon arrives and (in the absence of Dangerfield, and much to everybody's surprise) manages to succeed in the operation.
