He was waiting at the appointed place when Hetherwick hurried up next morning. Hetherwick immediately turned him down the lower side of the Fields.

"I've found out something about these people we're going to see," he said. "My clerk, Mapperley, told me a bit; he's a sort of walking encyclopædia. Old, highly respectable firm this. Penteney, senior, is retired; the firm is now really Blenkinsop & Penteney, junior. And Penteney, junior, is the Major Penteney who takes such an interest in Lady Riversreade's Home—and in Lady Riversreade. As I suggested last night, he was a Territorial officer—so now he's back at his own job. Now then, Matherfield, let's arrange our plan of campaign. You, of course, have your official credentials—I'm a deeply interested person, the man who chanced to witness Hannaford's death. I think you'd better be spokesman."

"Well, you'll come in when wanted?" suggested Matherfield. "You're better used to lawyers than I am, being one yourself."

"I fear my acquaintance with solicitors is, so far, extremely limited, Matherfield," replied Hetherwick with a laugh. "I have seen a brief!—but only occasionally. However, here we are at 853, and a solid and sombre old house it is."

The two callers had to wait for some time before any apparent notice was taken of their cards by the persons to whom they had been sent in. Matherfield was beginning to chafe when, at last, an elderly clerk conducted them up to an inner room wherein one cold-eyed, immobile-faced man sat at a desk, while another, scarcely less stern in appearance, in whom Hetherwick immediately recognised the Major Penteney pointed out by Rhona, stood, hands in pockets, on the hearthrug. Each stared silently at the two callers; the man at the desk pointed to chairs on either side of his fortress. He looked at Matherfield.

"Yes?" he asked.

"Mr. Blenkinsop, I presume?" began Matherfield, with a polite bow to the desk. "And Mr. Penteney?" with another to the hearthrug.

"Just so," agreed Blenkinsop. "Precisely! Yes?"

"You have my card, gentlemen, and so you know who I am," continued Matherfield. "The police——"

"A moment," interrupted Blenkinsop. He picked up Hetherwick's card and glanced from it to its presenter. "Mr. Guy Hetherwick," he remarked. "Does Mr. Hetherwick also call on behalf of the police? Because," he added, with a dry smile, "I think I've seen Mr. Hetherwick in wig and gown."
