With this parting counsel, spoken in a tone of strong conviction, the butler departed on his mission.
Although burning to know what Esther had said to Chalmers on her precipitate dash up the stairs, Roger felt his curiosity must remain unsatisfied for the present. At the moment all that mattered was her safety, already he had left her too long. He suddenly realised that he had been away at least five minutes, and assailed by fresh fears he hurried at once into the boudoir.
He entered confident of finding his aunt in charge of the situation. The next instant he cursed his folly in ever leaving the room. The old lady was not there. Instead, the clumsy figure bending over the couch and concealing its occupant from view was that of Sartorius. To his excited brain there was a sinister suggestion in the heavy body that approached so close to the girl lately terrified into unconsciousness. Roger did not stop to think. He strode forward and with a brusque movement caught hold of the man's arm and pulled him away. As he did so his nostrils detected a familiar odour and he caught sight of some object held in the doctor's hand. Was it a hypodermic syringe? A sick feeling swept over him.
"What are you doing to her?" he demanded furiously.
The doctor straightened up and for a second the two eyed each other in tense silence. Then a shadow of contempt passed over the taller man's face.
"My dear Mr. Clifford," he replied deliberately, "if you go away and leave this woman in a critical condition for a considerable length of time, you can hardly expect me not to do what I can for her. You may even admit that my knowledge of what is best is perhaps more extensive than yours."
Steadily Roger's eyes met the gaze of the doctor's little cold greyish ones.
"I don't question your superior knowledge, doctor," he replied with careful emphasis. "But I am not convinced that you were trying to revive her. How do I know"—he paused a moment, then continued slowly—"that you were not doing something to keep her unconscious?"
The suggestion amounted to a slap in the face. He watched keenly to note the result, and saw the heavy figure draw itself up to its full height, seeming at the same time to swell out. The broad face with its sloping, flattish forehead betrayed little if any change of expression.
"You overreach yourself, Mr. Clifford. Your gross insinuation compels me to go at once to Lady Clifford and inform her that I cannot remain longer under the same roof with a person who has so offensively outraged my professional dignity."
