"Gaol, did I say?" he exclaimed. "Why, this is a gaol! Look here, Mr. Hetherwick!—window morticed inside and fitted with iron bars outside. Even if whoever's been in here could have opened the window, and if there'd been no bars there, they couldn't have done anything though, for there's nothing but a high blank wall opposite—back of some factory or other, apparently. But what's this?" he added, opening a door that stood in a corner. "Um! small bathroom. And this," he continued, going to a square hatch set in the wall next to the staircase. "Ah! trap big enough to hand things like small trays through, but not big enough for a grown person to squeeze through. Well, I shouldn't wonder if you're right, Mr. Hetherwick—this, probably, is where these ladies were locked up. But—they're gone!"
Hetherwick was looking round. Suddenly his eyes lighted on a familiar object. He stepped forward, and from a chair near one of the beds, picked up a handbag of green silk. He knew it well enough.
"That settles it!" he exclaimed. "They have been here! This is Miss Han—I mean Miss Featherstone's bag—I've seen her carry it often. These are her things in it—purse, card-case, so on. She's left it behind her."
"Aye, just so!" agreed Robmore. "As I say, they all left in a hurry. I figure it out like this: the woman, who, of course, acted as sort of gaoler to these two unfortunate ladies, when she made that discovery round yonder, came back here, got her outdoor things, and cleared off. But before she went, she'd the decency to slip up here, undo that chain, slip the bolt back, and turn the key! Then, no doubt, she made tracks at express speed, leaving the ladies to do what they liked. And they, Mr. Hetherwick, having a bit o' common sense about 'em, did what I should ha' done—they hooked it as quick as possible. That's that, sir!"
Hetherwick thrust Rhona's handbag into his pocket and made for the door.
"Then I'm off, Robmore," he said. "I must try to find out where they've gone. I've an idea probably they'd go to Penteney's office. I'll go there. But—you?"
"Oh, I'm going back to Pencove Street," answered Robmore. "Plenty to do there. But off you go after the ladies, Mr. Hetherwick, there's nothing you can do round here now. I'll keep that clerk of yours a bit, and the Jew chap—they might come in. We shall have some nice revelations in the papers to-morrow, I'm thinking, especially if Matherfield has the luck he expects."
"What are you going to do about this house?" asked Hetherwick as they went downstairs. "Do you think the woman will come back?"
"Bet your life she won't!" answered Robmore. "Not she! I should think she's half-way across London—north, south, east or west, by this. House? Why, I shall just lock the front door and put the key in my pocket. We shall want to search this house narrowly."
Hetherwick bade him good-day for the time being, and hurried off to Victoria Street, to fling himself into the first disengaged taxi-cab he encountered, and to bid its driver go as speedily as possible to Lincoln's Inn Fields. He was anxious about Rhona—and yet he felt that she was safe. And he was inquisitive, too; he wanted to hear her story, to find out what had happened behind the scenes. He felt sure of finding her at Penteney's office; she and Madame Listorelle, once released from their prison, would naturally go there.
