“As I have already said, Farquhar has made a great discovery, and wishes at once to consult you. His indisposition was only temporary—an attack of giddiness,” he added, and he saw that she was wavering. “I’m an old friend of Frank’s,” he went on, “and he consulted me, as soon as the matter of the Hebrew secret came into his hands. Of course, he has very often mentioned you,” he laughed.

He was a well-spoken man, and beneath his smile the girl did not detect his cunning. Her natural caution was overcome by her frantic desire to see Frank, and hear what he had discovered. An instant’s reflection showed her that if he could not meet her it was only natural that he should send his friend Captain Wetherton—a man of whom he had spoken on several occasions. He was stationed at Hounslow, Frank had told her, and they often spent the evening together at the club and some “show” afterwards.

“There’s a ‘taxi’ across the way,” the Captain pointed out. “Let us take it—that is if I may be permitted to be your escort, Miss Griffin?”

“Is it far?”

“Oh, dear no,” he laughed, and raising his hand he called the cab he had already in waiting. The vehicle drew across, and as he entered after her he spoke to the man. He had already given him the address before he had approached her. As he sat by her side, the man’s face changed. In the semi-darkness she could not get a good look at his features, yet his chatter was gentlemanly and good-humoured. From his remarks it was apparent that he had known her lover for a long time, and held him in high esteem.

“As soon as Frank’s telegram arrived, I rushed out,” said the young girl. “It was a great surprise, for I believed him to be on his way to Copenhagen.”

“They’ll probably miss you at home, won’t they?” he asked, with a glance of admiration at the girl’s sweet face.

“Well,” she laughed, “my father doesn’t know I’m out. Laura, the maid, will leave the door unbolted and I’ve got the latch-key.”

The man seated at her side smiled, turning away his head lest she might wonder.

Acquainted as Gwen was with the streets of the West End, she saw that the course taken by the “taxi” was through Brompton Road and Knightsbridge to Hyde Park Corner, then straight up South Audley Street and across one of the squares, Grosvenor Square she believed it to be.
