The girl laughed and blushed as she bent down and touched Sartoris's cheek with her lips. A moment later they were gone, and Field had emerged from his hiding-place. He had discovered all that he required, for the present, and he decided not to take any further risks. The confused pieces of the puzzle were beginning to fit together in his mind, but they were by no means complete yet. Without further adventure the inspector crept back to the pantry and found himself at length in the road. He looked at the upstairs window whence the flickering signals had come, but it was all dark and still now, though it was not as yet late. "So far, so good," Field muttered to himself. "It strikes me that that young lady is likely to be of service to me. I'll find out who she is and whence she comes. And now to go off to the Comedy and see if I can get in touch with the little actress who must play her part in more dramas than one. I wonder if I had better see her at the theatre or follow her to her rooms. I'll be guided by circumstances." It was not more than half-past ten when Field reached the theatre. It was a popular house for the moment, where the management was running a kind of triple bill, consisting of one-act musical comedies, each of which contained the particular star artist. Two of the shows were already over, and the curtain was about to rise on the third, when Field reached the stage door. The inquiry for Miss Adela Vane was met by a surly request to know what was wanted. If the inquirer thought that he was going into the theatre he was jolly well mistaken. "So you just be off, or I'll call the police," the crusty doorkeeper said. "One way or another, I'm pestered out of my life by you chaps. Oh, you can leave a message or a bouquet or something of that kind, but it's long odds it's shoved into the dusthole." Field smiled as he produced his card and handed it over. The effect of the little square of shining pasteboard was marked and instantaneous. The man behind the bar was at once cringing and ready to do anything. "I'm sure I beg your pardon, sir," he said, "but we are pestered out of our lives from morning till night. I dare say I can get you a few words with Miss Vane, who does not come on the stage till the third piece. And from the bottom of my heart, I hope that there is nothing wrong, for a nicer young lady than Miss Vane----" "There is nothing wrong at all," Field hastened to say. "On the whole I've changed my mind. Don't say a word to Miss Vane about me, it may alarm her. Give me a programme; I'll just slip into the house and see Miss Vane from the stalls. Thank you." Field made his way round to the front of the house, and presenting his card at the box office, desired to have a seat for half an hour or so. CHAPTER XX
