# XIV: The Jacket explained — The Case with Nine Solutions

> Chapter companion for The Case with Nine Solutions by J. J. Connington.

## What happens

Inspector Flamborough and Sir Clinton Driffield visit the Croft-Thornton Institute to interrogate Dr. Markfield and Dr. Silverdale. Flamborough presents a torn piece of cloth with a button, stained with picric acid, and presses Markfield about its origin. Markfield initially evades, but after a threat of being an accessory to murder, he cooperates. Flamborough then questions Silverdale about his alibi for the night of the maid's murder, his lost cigarette holder, his banjo playing, and a torn and bloodstained laboratory coat. Silverdale cannot explain the coat's condition, and Markfield interjects that someone might have borrowed it. Flamborough seizes the coat as evidence and warns Silverdale about his silence.
