"Why?" asked Gebb, pertinently.
"Because I am certain that Dean is guilty."
"Admitting that he is--which I don't on the strength of the romantic vow--how did Ferris become possessed of the necklace?"
"I don't know. Only Ferris can explain that."
"Well, then, Mr. Alder, he won't explain. So on the face of it he is guilty, and Dean isn't."
"I tell you he is innocent!" said Alder, angrily, "and my friend Mr. Basson can prove it."
"Basson--Clement Basson, the barrister?" said Gebb, with a stare. "Why, what on earth has he got to do with it?"
"He saw Ferris on the night of the murder!"
"Saw him! Where?"
"At Grangebury! In the evening."
