The express was very fast, stopping only once—at Taunton. Here Cheyne, having satisfied himself that his quarry had not alighted, settled himself with an easy mind to await the arrival at Paddington. He dined luxuriously, and when at nine precisely they drew up in the terminus, he felt extremely fit and ready for any adventure that might offer itself.
From the pages of the many works of detective fiction which he had at one time or another digested, he knew exactly what to do. Jumping out as the train came to rest, he hurried along the platform until he had a view of the carriage in which the others had traveled. Then, keeping carefully in the background, he awaited developments.
Soon he saw the men alight, cross the platform and engage a taxi. This move also he was prepared for. Taking a taxi in his turn, he bent forward and said to the driver what the sleuths of his novels had so often said to their drivers in similar circumstances: “Follow that taxi. Ten bob extra if you keep it in sight.”
The driver looked at him curiously, but all he said was: “Right y’are, guv’nor,” and they slipped out at the heels of the other vehicle into the crowded streets.
Cheyne’s driver was a skillful man and they kept steadily behind the quarry, not close enough to excite suspicion, but too near to run any risk of being shaken off. Cheyne was chuckling excitedly and hugging himself at the success of his efforts thus far when, with the extraordinary capriciousness that Fate so often shows, his luck turned.
They had passed down Praed Street and turned up Edgware Road, and it was just where the latter merges into Maida Vale that the blow fell. Here the street was up and the traffic was congested. Both vehicles slackened down, but whereas the leader got through without a stop, Cheyne’s was held up to give the road to cross traffic. In vain Cheyne chafed and fretted; the raised arm of the law could not be disregarded, and when at last they were free to go forward, all trace of the other taxi had vanished.
In vain the driver put on a spurt. There were scores of vehicles ahead and a thousand and one turnings off the straight road. In a few minutes Cheyne had to recognize that the game was up and that he had lost his chance.
He stopped and took counsel with his driver, with the result that he decided to go back to Paddington in the hope that when the other taxi had completed its run it would return to the station rank. He had been near enough to take its number, and his man was able to give him the other driver’s address, in case the latter went home instead of to the station.
Having reserved a room at the Station Hotel and written a brief note to his sister saying that his business had brought him to London and that he would let her know when he was returning, he lit his pipe, and turning up the collar of his coat, fell to pacing up and down the platform alongside the cab rank. He was relieved to find that vehicles were still turning up and taking their places at the end of the line, and he eagerly scanned the number plate of each arrival. For endless aeons of time he seemed to wait, and then at last, a few minutes before ten, his patience was rewarded. Taxi Z1729 suddenly appeared and drew into position.
In a moment Cheyne was beside its driver.
