Punctual to the minute, Link, in a state of subdued excitement, came to Lucian's rooms. Already he had sent his two policemen over to the house, into which he had instructed them to enter in the quietest and most unostentatious manner, and now came to escort the barrister across.

Lucian put on his hat at once, and the two walked out into the dark night, for dark it was, with no moon, few stars, and a great many clouds. A most satisfactory night for their purpose.

"All the better," said Link, casting a look round the deserted square; "all the better for our little game. I wish to secure this fellow as quietly as possible. Here's the door open—in with you, Mr. Denzil!"

According to instructions, a policeman had waited behind the closed door, and at the one sharp knock of his superior opened it at once so that the two slipped in as speedily as possible. Link had a dark-lantern, which he used carefully, so that no light could be seen from the window looking on to the square; and with his three companions he went into the back room which had formerly been used by Clear as a sleeping apartment. Here the two policemen stationed themselves in one corner; and Link, with Lucian, waited near the door leading into the sitting-room, so as to be ready for Mrs. Clear.

All was so dark and lonely and silent that Lucian's nerves became over-strained, and it was as much as he could do to prevent himself from trembling violently. In a whisper he conversed with Link.

"Have you heard anything of that girl Rhoda?" he asked.

"We have traced her to Berkshire," whispered Link. "She went back to her gypsy kinsfolk, you know. I dare say we'll manage to lay hands on her sooner or later."

"She is an accomplice of Wrent's, I believe."

"So do I, and I hope to make him confess as much to-night. Hush!"

Suddenly Link had laid his clasp on Lucian's wrist to command silence, and the next moment they heard the swish-swish of a woman's dress coming along the passage. She entered the sitting-room cautiously, moving slowly in the darkness, and stole up to the door behind which Lucian and the detective were hiding. The position of this she knew well, because it was opposite the window.
