to the window--and started forward with surprise.
"Darby! By all the devils in Hell! Here, with the King. . . The
false-hearted scoundrel! With him, at least, I can square off."

He struck the door sharply; it opened and Raynor Royk stepped within
and saluted.

"Will you deliver a message for me?" Buckingham asked, offering him a
rose-noble.

The old soldier drew back.

"I am not for sale, Sir Duke," he said. "What is the message?"

"For Sir Aymer de Lacy, my good fellow. Tell him I pray a moment's
conversation on a matter of grave importance."

Without a word Royk faced about and went pounding down the passage.

Presently a light, quick step came springing up the stairway, and De
Lacy entered and closed the door behind him.

"You sent for me?" he said.

"Aye, Sir Aymer, and I thank you for the coming. Tell me, when did

That the Master of Horse was surprised at the summons was very evident;
and he turned to De Lacy questioningly.

"The Duke has certain information touching Lord Darby which must be
confided to some one else than me," Sir Aymer explained.

Ratcliffe nodded. "Since your quarrel with Lord Darby such a course
were very wise."

"I know nothing of Darby's quarrel with Sir Aymer de Lacy," said
Stafford, "but I have seen him here and have learned that he joined
Richard at Lincoln, the day prior to that set for the revolt, so I
denounce him as a double traitor--traitor to the King, forsworn to me.
It was he--he and that hawk-faced priest Morton--who, ere we left
Windsor and on all the march to Gloucester, urged and persuaded me to
turn against the King. He visited me at Brecknock to arrange details;
was there only four days before he
