"I am so glad," said the stranger, and in a flash stepped into the hall, and shut the door behind him.

"What are you doing?" said Miss Markham. "You must not come in here like that. Go away at once!"

"I know, my dear lady, it is quite unconventional and wrong, and I can only assure you if you had not been insured against burglary I should never have come in. You may believe me that in the exercise of my profession, I have always done my best to consult the feelings of others."

"Your profession! What profession?"

"We won't give it a name. 'What's in a name?' Some of my confrères are rough and violent; I am nothing of the kind. Naturally if you began to make a noise, I should have to take some steps to prevent it. The police in this neighbourhood are few in number and quite inefficient, and I think there is no other bungalow within a quarter of a mile."

Miss Markham was now alive to the state of the case.

"I think," she said, "that a police-whistle can be heard at that distance."

She raised her police-whistle just as he raised his revolver; the two hands went up together.

"Really, Miss Markham, you ought not to force me into such a totally false position. My feelings towards you are those of a chivalrous gentleman; it absolutely repels me to do anything whatever which would appear in the nature of a threat. You have put the police-whistle down? That's right. Now then we can talk about this necklace. It would be pleasanter if we sat down; we will go into the dining-room, shall we? I say the dining-room rather than the drawing-room, because I think you might possibly like to ask me to take a whisky-and-soda, and the decanters are there."

Miss Markham followed him into the dining-room; she did not ask him to take a whisky-and-soda. Notwithstanding this, he took it.
