“They may or may not,” was the reply, “and--” he hesitated, “I don’t think I should talk about this to Miss Ardfern. In fact, I would rather you didn’t.” Tab had had no intention of alarming Ursula, and he could make that promise without reservation. XXXI She came to Doughty Street and picked him up and they were at Stone Cottage in time for lunch. The weather was still unsettled, but Tab had passed the stage where weather made any difference to him. Though he did not tell her of his sensational experience, he did mention his dream. “Ursula?” he asked. “You like Yeh Ling, don’t you? So do I, as a matter of fact, but do you absolutely trust him?” She considered before she spoke. “Yes, I think I do,” she said. “He has been a most faithful friend. Think, Tab, without my knowledge, all these years he has been watching over me. I should be a most ungrateful girl if his loyalty did not move me.” Tab thought that there might be some other explanation of Yeh Ling’s devotion but wisely said nothing. “Do you know,” she said, “that he keeps a man watching this house day and night? I only discovered it by accident when I was engaged in revolver shooting. Perhaps Yeh Ling told you that I nearly shot one of his sentinels.” “He is a strange man,” admitted Tab, “but my dream rather impressed me--” “Even the first part of your dream hasn’t come true yet,” she suggested demurely and he picked her up in his arms there and then. Happily the so-easily scandalized Mr. Turner was engaged elsewhere. His heart was full of love and gratitude when he left her in the sweet-smelling dusk and mounting his bicycle, which he had brought strapped to the back of Ursula’s car, started on his leisurely way home. Half-way he had a puncture which delayed him, and it was nearly ten o’clock when he wheeled the machine into the garage where it was maintained. The last part of the journey was made through a heavy driving rain and he was wet through by the time he reached Doughty Street. A hot bath and a change of clothing brightened him and he was filling his cigarette case preparatory to going out to take a meal, when he was called to the telephone. He expected to be greeted by Carver but it was Rex who was speaking and his voice was eager and urgent. “Is that you Tab? My boy, I’ve made the most wonderful discovery!” “What is that?” asked Tab wondering. “You are not to breathe a word to Carver, you understand, Tab? This is the most extraordinary discovery. Tab!” his voice shook, “I have found how the murder was committed!” “The Trasmere murder?” “Yes,” came the quick reply. “I know how the man got in and out of the vault. I was in there this afternoon inspecting the work that has been done and I found it by accident. It is all so simple, Tab, how the key got on to the table, and--everything. Can you meet me at Mayfield?” “At Mayfield?” “I’ll be waiting outside the door for you. I don’t want any of Carver’s men to see us.” “Why not?” asked Tab.
