“That stair curves down to the ground floor,” he explained. “It comes out through the side wall inside the big fireplace in the hall. To open the panel down there you press a button under the left-hand corner of the mantel. To close either panel you simply put it down, once you’re inside.”
“Are there any more of these passages in the walls?”
“Very likely, but I haven’t found them yet. Winncote is an exact copy of the Doctor’s ancestral home in Wales. Those old houses were honeycombed with priest holes, secret passages and whatnot. And Doctor Winn had his architect copy the original Winncote across the water down to the last stone, with modern improvements such as bathrooms and steam heat, added.”
“Funny old fellow, isn’t he?” commented Dorothy sleepily. “Then I’m simply to carry on until I hear from you again?”
“That’s right. But whatever you do, watch your step with the Lawson woman. She is fully as heartless as she is beautiful. If you had never heard of that meeting in the Jordans’ flat, it would be much better for you. She will try to trap you, so please be on your guard continually. Well, good night, again.”
“Good night, Mr. Tunbridge.”
The panel in the back wall of the closet slid into place, and Dorothy went back to bed. She realized now that this matter of impersonating her cousin was not going to prove to be the easy job she had fancied. A slip on her part now would not only put her own life in danger, it would probably ruin all government plans to apprehend these desperate criminals.
At last she fell into a troubled sleep wherein she dreamed that a long circular staircase curved round and round her bedroom, and that Mrs. Lawson, dressed as a butler, had set her to watch every step of it.

GRETCHEN
Dorothy awoke from troubled dreams to find that it was another day. Through the open window she saw the swirl of snowflakes driven in a high wind. The bedroom was cold and in the grey light of the winter morning it had lost its cheerful air.
