Dawson gulped down a cup of coffee, sadly regarded his rapidly congealing bacon, and skipped off to the dockyard. "Who is this man of yours whose mother has died at so very inconvenient a moment for us? What the deuce is he doing with a mother in Essex at all? He ought to be a Devon man."

"He isn't, anyway. I have been making close inquiries. Though he has been with us for sixteen years, he did come originally from somewhere in the East. The man is one of the best I have—never drinks, keeps good time, and works hard. He makes big wages, and carries them virtuously home to his wife. He has money in the savings bank, and holds Consols, poor chap, on which he must have wasted the good toil of years. I can't imagine any one less likely to take German gold than this man Maynard. Sure you haven't a bee in your bonnet, Dawson? To a police officer every one is a probable criminal, but some of us now and then are passably honest. I will bet my commission that Maynard is honest."

Dawson sniffed. "The honest men, with the excellent characters and the virtuous wives, are always the most dangerous because least likely to arouse suspicion. How do you know that Maynard hasn't a second establishment hidden away somewhere in the Three Towns? The upper and middle classes have no monopoly in illicit love affairs. Their working class betters do a bit that way too."

"All right. Have it your own way. We will assume for the sake of security that Maynard is a spy, that he has no dead mother whom he wants leave to bury, and that he has sold his country for the sake of some bit of fluff in Plymouth. The point is: what am I to do? Shall I grant leave?"

"Yes," said Dawson, "and do it handsomely. Give him four days and run the sympathetic stunt. Offer him a Service pass by the Great Western. Say how grieved you are and all the rest of the tosh. Have him up now, and put me somewhere close so that I can take a good look at the swine when he comes in and when he goes out."

The Chief of the Dockyards shrugged his shoulders, placed Dawson in an adjoining room, and summoned Maynard from the yard. The man, who was dressed in the awful dead black of his class when a funeral is in prospect, came up, and Dawson got a full sight of him. Maynard was about thirty-five, well set up—for he had served in the Territorials—and looked what he was, a first-rate workman of the best type. Even Dawson, who trusted no one, was slightly shaken. "I have never seen a man who looked less like a spy," muttered he; "but then, those always make the most dangerous of spies. Why has he a mother in Essex, and why has she died just now? Real mothers don't do these things; they've more sense."

Maynard received his third-class pass, respectfully thanked his Officer for his kindly expressed sympathy—which in his case was quite genuine—and disappeared. Dawson jumped into the room again to take a word of farewell. "I should know him anywhere," he cried. "I am going by the same train in the same carriage. Good-bye."

Maynard reached the Great Western station in good time, and found a carriage which was not overcrowded. He was carrying a small handbag. At the last moment before the train started a prosperous-looking passenger, with "commercial gentleman" written all over him, stepped into the same compartment and seated himself in a vacant seat opposite the bereaved workman. It was Dawson in one of his favourite roles. "There is nothing less like a detective," he would say, "than a middle-aged commercial traveller. They are such genial, unsuspicious, open-handed folk. This comes of wandering about the country at other people's expense."

The 10.15 fast express from the Three Towns to Paddington is an excellent one, and the journey was not more tedious than five hours spent in a train are bound to be. All through the journey Dawson, from behind his stock of papers and magazines, studied Maynard, and became, not, perhaps shaken in his conviction, but certainly puzzled. "He looked," he explained to me, "like a sick and sorrowful man. One who had really lost a beloved mother far away would look just like that. But so might one who had been unfaithful to a trusting wife and was now risking his neck to pour gold into the greedy lap of a frowsy mistress. One must never judge by appearances. A man may look as sick over backing the wrong horse as at losing an only son in the trenches. Human means of expression are limited."

"It takes time to learn that you are not such a beast as you pretend,"
I observed. Dawson grinned.
