“London is simply unbearable!” she declared. “It’s ever so many degrees hotter than at Atworth, and in the Stores it is awfully stuffy. In the provision department butter, bacon, and things seem all melting away.”

“You’ll be glad to get back again to Wiltshire,” I laughed.

“Very. We shall go by the night-mail to-morrow,” she answered. “Why don’t you come up and visit us, Doctor? My husband would be charmed to meet you I’m sure.”

“That’s just what I’ve been saying, dear,” exclaimed Beryl. “Do persuade Doctor Colkirk to come.”

“I am sure you are both very kind,” I replied, “but at present I am in practice.”

“You can surely take a holiday,” urged Beryl. “Do come. We would try to make it pleasant for you.”

Her persuasion decided me, and, after some further pressing on the part of her ladyship, I accepted the invitation with secret satisfaction, promising to leave in the course of a week or ten days.

Then we fell to discussing the curious phenomena of the previous night, until, having again exhausted the subject, I rose to take my leave.

“Good-bye, Doctor Colkirk,” Beryl said, looking into my eyes as I held her small hand. “I hope we shall soon meet down in Wiltshire, and, when we do, let us forget all the mystery of yesterday.”

“I suppose you have given Hoefer permission to visit, the room when he wishes to pursue his investigations?” I said, turning to her ladyship.
