In A Case For Doctor Morelle #8, "Act Of Violence," Doctor Morelle and his secretary Miss Frayle travel to the Essex countryside to visit Professor Stenberg. On their way, they stop at a garage for directions and encounter a young man who seems strangely disturbed by the doctor's presence. Miss Frayle notices the man's reaction when he hears Doctor Morelle's name, and the doctor cryptically mentions recognizing him from a previous "sordid, lurid affair." The man is Robert Benson, whose name appears on a poster advertising a local concert performance.

When they arrive at Professor Stenberg's house, the peaceful visit is disrupted when Benson appears in the garden beneath Miss Frayle's balcony. He desperately insists on speaking with Doctor Morelle, warning Miss Frayle that it's for the doctor's own good. Benson is agitated and defensive, believing the doctor has deliberately come to the area to investigate him. The young man was previously convicted of murder at the Old Bailey, a trial Doctor Morelle attended, though he insists he's innocent. As tensions mount, Doctor Morelle agrees to meet with the clearly troubled young man to discover what he wants.
