Jimmy Brown

In the short story Death by Drowning, Jimmy Brown is a twelve year old boy in the village of St. Mary Mead. He is one of the chief witnesses of the drowning of Rose Emmott. He heard a splash and a scream at about the time of the incident from the area of the bridge where it was assumed she fell off. He also told police that he had seen Rex Sandford walking up in the woods near the bridge about ten minutes or so before he heard the scream. On the other side of the bridge, the village side, he saw a man whistling while walking and thought he might be Joe Ellis. Some way away he also saw two men with a wheelbarrow.

Jimmy Brown is described as intelligent although rather small for his age. He has a sharp, cunning face. He was eager to be questioned by the police and "rather disappointed when checked in his dramatic tale".

Sir Henry Clithering commended Jimmy Brown for his presence of mind, adding that he must be a boy scout, which Jimmy confirmed.
