his tone very gentle. But
Mr. Sabin, who seldom yielded to any passionate impulse, kept his teeth
set and his hand clenched, lest the blow he longed to deal should escape
him.

"At midday to-morrow I shall be pleased to receive you," he said.
"The Countess, with her usual devotion and good sense, has, I trust,
convinced you that our action is necessary!"

"To-morrow at midday," Mr. Sabin said, "I will be here. I have the
honour to wish you all good-night."

His farewell was comprehensive. He did not even single out Lucille for a
parting glance. But down the broad stairs and across the hall of Dorset
House he passed with weary steps, leaning heavily upon his stick. It was
a heavy blow which had fallen upon him. As yet he scarcely realised it.

His carriage was delayed for a few moments, and just as he was entering
it a young woman, plainly dressed in black, came hurrying out and
slipped a note into his hand.

"M. C."

Mr. Sabin leaned back in his carriage, and a frown of faint perplexity
contracted his forehead.

"If I were a younger man," he murmured to himself, "I might believe
that this woman was really in earnest, as well as being Saxe Leinitzer's
jackal. We were friendly enough in Paris that year. She is unscrupulous
enough, of course. Always with some odd fancy for the grotesque or
unlikely. I wonder--"

He pulled the check-string, and was driven to Camperdown House. A great
many people were coming and going. Mr. Sabin found Helene's maid, and
learnt that her mistress was just going to her room, and would be alone
for a few minutes. He scribbled a few words on the back of a card, and
was at once taken up to her boudoir.

"My dear UNCLE," Helene exclaimed, "you have arrived most opportunely.
We have
