These proceedings were not in accordance with the Plan. The intention had been that on either recovering the tracing or satisfying himself that it was not in the house, Cheyne would close the back door, and letting himself out by the front, would meet Joan, pull the door to after them, walk round the house and quietly disappear via the garden and lane. But the possibility of an unexpected flight had been recognized. It had been decided that in such a case the first thing would be to get rid of the tracing, so that in the event of capture, the fruits of the raid would at least be safe. Therefore, on all the routes away from Earlswood hiding places had been fixed on, from which Joan would afterwards recover it. Along the lane the hiding place was the back of a wall approaching a culvert, and over this wall Cheyne duly threw the booty as he rushed along.
By this time Dangle was out on the road and running for all he was worth. But Cheyne had the advantage of him. He was lighter and an experienced athlete, and, except for his illness, was in better training. Moreover, he was more lightly clad and wore rubber shoes. Dangle, though Cheyne did not know it, was hampered by an overcoat and patent leather boots. He could not gain on the fugitive, and Cheyne heard his footsteps dropping farther and farther behind, until at last they ceased altogether.
Cheyne slacked to a walk as he wiped the perspiration from his forehead. So far as he was concerned he had now only to make his way back to town and meet Joan at her studio. He considered his position and concluded his best and safest plan would be to go on to Harrow and take an express for Marylebone—if he could get one.
He duly reached Harrow, but he found there that he would have nearly an hour to wait for a non-stop train for London. He decided, however, that this would be better than risking a halt at Wembley Park, and he hung about at the end of the platform until the train came along. On reaching town he took a taxi to Horne Terrace and hurried up to No. 12. Joan had not returned!
He waited outside her room for a considerable time, then coming down, began to pace the street in front of the house. Every moment he became more and more anxious. It was now half past twelve o’clock and she should have been back over an hour ago. What could be keeping her? Merciful Heavens! If anything could have happened to her.
He wrote a note on a leaf of his pocketbook saying he would return in the morning, and going once more up to her flat, pushed it under the door. Then hailing a belated taxi, he offered the man a fancy price to drive him to Wembley Park.
Some half-hour later he climbed over the wall across which he had thrown the tracing. A careful search showed that it was no longer there; moreover it revealed the print of a dainty shoe with a rather high heel, such as he had noticed Joan wearing earlier in the evening. He returned to the shrubs at the gap where they had waited, but there he could find no trace of her at all. Then he walked all round Earlswood, but it was shrouded in darkness. Finally, his taximan having refused to wait for him and all traffic being over for the day, he set out to walk to London, which he reached between three and four o’clock.
He had some coffee at a stall and then returned to his hotel, but by seven he was once more at Horne Terrace. Eagerly he raced up the steps and knocked at No. 12. There was no answer.
Suddenly a white speck below the door caught his eye, and stooping, he saw the note he had pushed in on the previous evening. Joan evidently had not yet returned.
