There was a deep silence. Tarling could feel his heart thumping almost noisily.

"After I had left Lyne's Store," she said, "I had decided to go to mother to spend two or three days with her before I began looking for work. Mr. Milburgh only went to Hertford for the weekends, and I couldn't stay in the same house with him, knowing all that I knew.

"I left my flat at about half-past six that evening, but I am not quite sure of the exact time. It must have been somewhere near then, because I was going to catch the seven o'clock train to Hertford. I arrived at the station and had taken my ticket, and was stooping to pick up my bag, when I felt a hand on my arm, and turning, saw Mr. Milburgh. He was in a state of great agitation and distress, and asked me to take a later train and accompany him to the Florentine Restaurant, where he had taken a private room. He told me he had very bad news and that I must know.

"I put my bag in the cloak-room and went off with him, and over the dinner--I only had a cup of tea, as a matter of fact--he told me that he was on the verge of ruin. He said that Mr. Lyne had sent for a detective (which was you), and had the intention of exposing him, only Mr. Lyne's rage against me was so great, that for the moment he was diverted from his purpose.

"'Only you can save me,' said Milburgh.

"'I?' I said in astonishment, 'how can I save you?'

"'Take the responsibility for the theft upon yourself,' he said. 'Your mother is involved in this heavily.'

"'Does she know?'

"He nodded. I found afterwards that he was lying to me and was preying upon my love for mother.

"I was dazed and horrified," said the girl, "at the thought that poor dear mother might be involved in this horrible scandal, and when he suggested that I should write a confession at his dictation and should leave by the first train for the Continent until the matter blew over, I fell in with his scheme without protest--and that is all."

"Why did you come to Hertford to-night?" asked Tarling.

Again she smiled.

"To get the confession," she said simply "I knew Milburgh would keep it in the safe. I saw him when I left the hotel--he had telephoned to me and made the appointment at the shop where I slipped the detectives, and it was there that he told me----" she stopped suddenly and went red.

"He told you I was fond of you," said Tarling quietly, and she nodded.

"He threatened to take advantage of that fact, and wanted to show you the confession."

"I see," said Tarling, and heaved a deep sigh of relief. "Thank God!" he said fervently.

"For what?" she asked, looking at him in astonishment.

"That everything is clear. To-morrow I will arrest the murderer of Thornton Lyne!"

"No, no, not that," she said, and laid her hand on his shoulder, her distressed face looking into his, "surely not that. Mr. Milburgh could not have done it, he could not be so great a scoundrel."

"Who sent the wire to your mother saying you were not coming down?"

"Milburgh," replied the girl.

"Did he send two wires, do you remember?" said Tarling.

She hesitated.

"Yes, he did," she said, "I don't know who the other was to."

"It was the same writing anyway," he said.

"But----"

"Dear," he said, "you must not worry any more about it. There is a trying time ahead of you, but you must be brave, both for your own sake and for your mother's, and for mine," he added.

Despite her unhappiness she smiled faintly.

"You take something for granted, don't you?" she asked.

"Am I doing that?" he said in surprise.

"You mean--" she went redder than ever--"that I care enough for you-............
