“I feel confident of it. The Count is furious at the failure of the conspiracy against Mr Merton Mansfield. He came to see father last night. I did not gather much, as I had to get away to the theatre, but I overheard him suggest that some other method should be tried,” replied Ella Drost.

She was sitting in the dainty little drawing-room of the flat in Stamfordham Mansions, chatting with her airman lover.

“Of course,” he said. “Ortmann and your father were well aware that Merton Mansfield is still the strongest man in the whole Government, a marvellous organiser, and the really great man upon whom Britain has pinned her faith.”

“They mean to work some evil upon him,” the girl said apprehensively. “I’m quite certain of it! Cannot we warn him?”

“I did so. I wrote to him, urging him to take precautions, and declaring that a plot was in progress,” said Kennedy. “I suppose his secretary had the letter and probably held it back in order not to disturb him. Secretaries have a habit of doing that.”

Ella, whose cigarette he had just lit, blew a cloud of blue smoke from her lips, and replied:

“Well, if that’s the case then it is exceedingly wrong. The greatest care should be taken of those who are leading us to victory. Ah! dearest,” she added with a sigh, “you do not know how bitter I feel when I reflect that my own father is a German and, moreover, a most deadly enemy.”

“I know, darling, I know,” the man responded. “That’s the worst of it. To expose the organiser of these conspirators would be to send your own father to prison—perhaps to an ignominious end.”

“Yes. All we can do is to watch closely and thwart their devilish designs, as far as we are able,” the girl said.

“Unfortunately, I’ll have to go back to the air-station to-night, but I’ll try to come up again for the week-end.”
