ot
long, however, did that salon merely stare at the celebrated American;
his lateness had already become a domestic problem, and he was sent with
all speed into the dining-room with Lady Galloway on his arm.

Except on one point the Galloways were genial and casual enough. So long
as Lady Margaret did not take the arm of that adventurer O'Brien, her
father was quite satisfied; and she had not done so, she had decorously
gone in with Dr. Simon. Nevertheless, old Lord Galloway was restless and
almost rude. He was diplomatic enough during dinner, but when, over the
cigars, three of the younger men--Simon the doctor, Brown the priest,
and the detrimental O'Brien, the exile in a foreign uniform--all melted
away to mix with the ladies or smoke in the conservatory, then the
English diplomatist grew very undiplomatic indeed. He was stung
every sixty seconds with the thought that the scamp O'Brien might be
signalling to Margaret somehow; he did not attempt to imagine how. He
was left over the coffee with Brayne, the hoary Yankee who believed
in all religions, and Valentin, the grizzled Frenchman who believed in
none. They could argue with each other, but neither could appeal to
him. After a time this "progressive" logomachy had reached a crisis of
tedium; Lord Galloway got up also and sought the drawing-room. He lost
his way in long passages for some six or eight minutes: till he heard
the high-pitched, didactic voice of the doctor, and then the dull voice
of the priest, followed by general laughter. They also, he thought with
a curse, were probably arguing about "science and religion." But the
instant he opened the salon door he saw only one thing--he saw what
was not there. He saw that Commandant O'Brien was absent, and that Lady
Margaret was absent too.

Rising impatiently from the drawing-room, as he had from the
dining-room, he stamped along the passage once more. His notion of
protecting his daughter from the Irish-Algerian n'er-do-weel had become
something central and even mad in his mind. As he went towards the back
of the house, where was Valentin's study, he was surprised to meet his
daughter, who swept past with a white, scornful face, which was a second
enigma. If she had been with O'Brien, where was O'Brien! If she had
not been with O'Brien, where had she been? With a sort of senile and
passionate suspicion he groped his way to the dark back parts of the
mansion, and eventually found a servants' entrance that open
