when danger threatens ane o' the M'Gregors or any they love."

Stuart restrained a smile, and, "A well-meaning but melancholy
retainer!" he commented.

"As well as I hear you now, laddie, I heard the pibroch on the day a
certain woman first crossed my threshold, nigh thirty years ago, in
Inverary. And as plainly as I heard it wailing then, I heard it the
first evening that Miss Dorian came to this house!"

Torn between good-humoured amusement and real interest, "If I remember
rightly," said Stuart, "Mlle. Dorian first called here just a week ago,
and immediately before I returned from an Infirmary case?"

"Your memory is guid, Mr. Keppel."

"And when, exactly, did you hear this Warning?"

"Twa minutes before you entered the house; and I heard it again the
now."

"What! you heard it to-night?"

"I heard it again just the now and I lookit out the window."

"Did you obtain a glimpse of Rob Roy's piper?"

"Ye're laughing at an old wife, laddie. No, but I saw Miss Dorian away
in her car and twa minutes later I saw yourself coming round the
corner."
