Answer: The Groundskeeper
Step-by-step explanation:
In Sancho and Bolsa, both men are detectives who are looking for William Morningstar who had been missing for 3 weeks. They go to the cemetery where William's parents were buried in order to look for clues.
They meet the Groundskeeper and Sancho pretends to be looking for a job as pretence to strike up a conversation to find out whether the groundskeeper had any information on William.
