“No, I quite admit that; and, of course, Mr. Tempest may know a lot of other details that upset what I’ve told you. But just ask him if he knew young Deverell.”

Yardley passed on his conversation with Parkyns to Tempest at the earliest opportunity.

“No,” the barrister at once said. “I know nothing about Deverell. What you tell me is most important;” and once again Tempest’s wits were started in a new direction. That such a person as young Deverell existed he did know, but of his character he was entirely ignorant. The man belonged to a younger generation, and the two had never happened to meet.

The hint of Parkyns opened up a new position. Deverell might have forged the one bill. Whoever did had had access to or had copied the firm’s notepaper. Having successfully discounted one bill it was quite likely a second attempt might be made; and Sir John Rellingham, likely enough, would write personal letters to Lord Deverell, from which his writing and signature could be copied. But Tempest could not think out that supposition any further: nor could he fit it in any way with the discovery of the revolver in Baxter’s suit-case. Involuntarily his suspicions harked back to Smith, and the barrister turned his mind to the possibility of breaking up the alibi which Smith put forward. The alibi given at the coroner’s inquest had certainly never been subjected to cross-examination. Such was the point at which matters stood when an entirely new development occurred. Marston came round to Tempest’s chambers, and, their greeting over, placed a gold watch and chain on the table. “Tempest, this was Sir John’s,” he said.

“Well, how can they help?” said the barrister, picking them up.

“Open the back. I only saw that the back opened yesterday. It’s a keyless watch; and though I bought it at the sale of Sir John’s things I never thought of opening it till yesterday.” Tempest opened the watch, and almost jumped from his seat in his astonishment.

“Look there!” he almost shouted, as he pointed to the miniature hanging on the wall, and then held out, for the other man to compare with it, the portrait inside the case. The two faces were identical.

“Who is it, Tempest?”

“That miniature is Dolores Alvarez, who died twenty years ago, and it’s the living image of Evangeline Stableford, who was murdered the other day.”

“Then, which of the two did Sir John know? Whose portrait was he carrying?”
