"So much I know," said Merrington.

"Then you are probably aware that Captain Nepcote was also present that evening, and brought several other young officers with him. It was he who introduced Philip Heredith to the girl whom he afterwards married."

"I knew Nepcote was a guest at one of the dances, but it is news to me that he introduced the girl to young Heredith. Lady Vaughan did not tell us this."

"Lady Vaughan did not know. I ascertained the fact later from one of the guests who witnessed the introduction. I attach some importance to the point. Last winter Philip Heredith and Nepcote were on fairly intimate terms, working together in the same room at the War Office, and sometimes going together to the houses of mutual friends. It was evidently a case of the attraction of opposites."

"It must have been," replied Merrington emphatically. "I have had inquiries made about Nepcote, and I should not have thought he would have appealed to Mr. Heredith. There is nothing actually wrong so far as we can learn, but he had the reputation, before the war, of a fast and idle young man about town, with a weakness for women and gambling. He came into a few thousands some years ago, but soon spent it. I imagine that he has subsisted principally on credit and gambling since he squandered his money, for he is certainly not the type of man to live on his pay as an officer. As a matter of fact, he was in serious trouble with the Army authorities recently for not paying his mess bills in France. He was not brought up to the Army, and he has seen very little active service. He got his captain's commission about twelve months after the war commenced, when the War Office was handing out commissions like boxes of matches, but he managed to keep under the Whitehall umbrella until quite recently. He seems to have a bit of a pull somewhere, though I cannot find out where. Perhaps it is his charm of manner—everybody who knows him says he has a charming manner, though it wasn't apparent to me that night I interviewed him at his flat."

"Perhaps he was too afraid to exercise it on that occasion," suggested Colwyn, with a smile. "He must have thought that it was all up with him."

"Have you discovered anything about Mrs. Heredith's antecedents?" asked Merrington with an abruptness which suggested that he had little relish for the last remark.

"Very little, apart from the fact that she lived in rooms, and had no real girl friends, so far as I can ascertain. Apparently she was a girl who played a lone hand, as they say in America. The type is not uncommon in large cities. My information, such as it is, is not of the least importance one way or the other."

"I have learnt very little more than you, except that she changed her rooms pretty frequently, but always kept within an easy radius of the West End, living in dull but respectable neighbourhoods like Russell Square and Woburn Place. It was precious little time she spent there, though. The people of these places know nothing about her except that she used to go out in the morning and did not return till late at night—generally in a taxi, and alone, so far as is known. She was, apparently, one of those bachelor girls who have sprung into existence in thousands during the war—one of that distinct species who trade on their good looks and are out for a good time, but keep sufficiently on the safe side of the fence to be careful of their reputations. It's part of their stock in trade.

"Such girls contrive to go everywhere and see everything at the expense of young men with more money than brains, who have been caught by their looks. It's the Savoy for lunch, a West End restaurant for dinner, revue, late supper, and home in a taxi—with perhaps, a kiss for the lot by way of payment. The War Office was a godsend to this type of girl. It gives them jobs with nothing to do, with a kind of official standing thrown in, and the chance of meeting plenty of young officers over on leave from the front, with money to burn and hungry for pretty English faces. It is difficult to find out anything about these bachelor girls. They have no homes—only a place to sleep in—they confide in nobody, and their men friends will never give them away. Almost any woman will give away a man, but I have never yet known a man give away a woman."
