“Captain Gordon heard your voice on a wireless telephone in the middle of the night, and wanted to know all about it,” said her father.

If he was relieved, he was also troubled. Looking at him, Elk suddenly saw the relief intensified, and with his quick intuition guessed the cause before John Bennett put the question.

“Was it Ray?” he asked eagerly. “Did he come down?”

She shook her head.

“No, father,” she said quietly. “And as to the wireless telephone, I have never spoken into a wireless telephone, and I don’t think I’ve ever seen one,” she said.

“Of course you haven’t,” said Dick. “Only we were rather worried when we heard your voice, but Mr. Elk’s explanation, that it was somebody speaking whose voice was very much like yours, is obviously correct.”

“Tell me this, Miss Bennett,” said Elk quietly. “Were you in town last night?”

She did not reply.

“My daughter went to bed at ten,” said John Bennett roughly. “What is the sense of asking her whether she was in London last night?”

“Were you in town in the early hours of this morning, Miss Bennett?” persisted Elk, and to Dick’s amazement she nodded.
