"I mean disguise yourself," said Dorothy, dropping her eyes beneath his gaze.
"Why?" The interrogation was rapped out in such a tone as to cause the girl to shrink back slightly.
"They wouldn't know and then it wouldn't——" she hesitated.
"Wouldn't what?" he demanded.
"Get your goat," said Dorothy after a moment's hesitation.
He continued to gaze intently at Dorothy, who was absorbed in a blank page of her note-book.
"Here, take this down;" and he proceeded to dictate.
"MY DEAR MR. BLAIR,—
"I am in receipt of yours of to-day's date. Will you tell Sir Lyster that I have bought a machine-gun, a blue beard, false eyebrows, and Miss West and I are going to do bayonet drill every morning with a pillow.
"With kind regards,
"Yours sincerely."
