"A big foot or a little foot?" asked Jack quickly.

"It is rather a big foot," said the detective, "and it has rubber heels. We traced it to a gate at the back of your premises, and the gate has been opened recently--probably by Mr. Meredith when he came to the house. It's a queer case, Mr. Rennett."

"What is the pistol?"

"That's new too," said Colhead. "Belgian make and impossible to trace, I should imagine. You can't keep track of these Belgian weapons. You can buy them in any shop in any town in Ostend or Brussels, and I don't think it is the practice for the sellers to keep any record of the numbers."

"In fact," said Jack quietly, "it is the same kind of pistol that killed Bulford."

Colhead raised his eyebrows.

"So it was, but wasn't it established that that was Mr. Meredith's own weapon?"

Jack shook his head.

"The only thing that was established was that he had seen the body and he picked up the pistol which was lying near the dead man. The shot was fired as he opened the door of Mr. Briggerland's house. Then he saw the figure on the pavement and picked up the pistol. He was in that position when Miss Briggerland, who testified against him, came out of the house and saw him."
