He was a small man, but he looked quite important as he made this boast. Whatever his failings, a want of confidence in himself was not one of them. But Farquhar still appeared dubious.

“I was a little doubtful till last night when I saw your friends at the restaurant,” went on Moreno, in his slightly husky voice. “You did not introduce me, there was no opportunity for that. I recognised one of them, Guy Rossett, who, I take it, is the fiancé of that charming young lady who, you say, is your cousin.”

Farquhar frowned a little. How quick these foreigners were to guess things.

“I have no idea,” he said stiffly. “General Clandon is my uncle, and I have been on very intimate terms with him and his family since I was a child. If there were any engagement, I think I should have been informed.”

Moreno noticed the frown, the stiffness in the tone. He went on smoothly.

“I may be jumping at conclusions rather too hastily, but I will tell you how I arrived at them. I happen to know that Guy Rossett is appointed to the Embassy at Madrid. With his sister, he dines with this charming girl and a man, obviously her father. It looks to me like a farewell dinner, and at a restaurant which is excellent, but certainly not fashionable. They wanted to escape observation, otherwise a man in Rossett’s position, and he was certainly the host, would have been at the Ritz.”

“And what do you deduce from these profound observations, worthy of Sherlock Holmes himself?” asked Farquhar a little testily.

Moreno answered slowly. He could see that his friend was troubled, but he had gone too far to recede.

“I should say there was a secret understanding between the young people, approved of by the girl’s father, and the man’s sister. Probably they are still waiting for the Earl’s consent to an open engagement.”

Farquhar, to hide his agitation, swallowed his whiskey and soda in one draught, and chewed viciously at the end of his cigar.
