Brittles opens the door to admit a Bow Street officer. The officer sends Brittles out to dispatch the coach. The officer introduces himself as Blathers, and his partner Duff.
Mr. Losberne tells the men the details of the robbery. Blathers concludes this robbery wasn’t done by someone from the country. They ask about the boy the servants mentioned. The doctor tells them that the servants thought the boy was connected because he was wounded, but their assumption was wrong. Blathers asks the boy’s history and where he came from. The doctor says he has heard the boy’s history, then quickly asks if the officers would like to view the area where the robbers broke in. Blathers agrees, saying they will want to question the servants after surveying the premises.
Giles and Brittles re-enact the robbery, contradicting each other in details.
Meanwhile, the doctor confers with Rosr and Mrs. Maylie. Rose asks if the child’s story would exonerate him. The doctor doubts it. Though he believes the boy, he doubts the officers will. The only parts of Oliver’s story that can be proven would count against him.
Blathers and Duff enter, saying they believe there is a possibility the servants were involved with the robbery. There were two men and a boy. They demand to speak to Oliver.
The doctor suggests that Mrs. Maylie offer the officers a drink first. The officers gladly accept. They tell Rose about a man who had been supposedly robbed. He sent the police on a wild goose chase, and then it turned out he had taken the money.
Afterwards, Mr. Losberne takes them up to see Oliver, who is disoriented by a fever. He tells them Oliver was accidentally injured by a spring gun while playing in a neighboring field. The butler had thought he was the boy with the robbers because of the wound he believe he gave him. Mr. Giles is suddenly doubtful that Oliver is the boy after all.
Brittles tells the officers he only thought Oliver had been the boy because Giles had been so certain. The officers examine the gun Giles claimed he shot the boy with who was with the robbers. They don’t find any bullets (for the doctor had removed them beforehand). Giles is relieved that it wasn’t he who shot Oliver after all.
The next day, two men and a boy are arrested and believed to be the trio who committed the robbery.
Oliver continues to improve under the care of the kind-hearted doctor, Mrs. Maylie, and Miss Rose.
