To begin with, the inspector's indisposition confined him to his flat. It held Nora there in the part of a nurse. It drew Garth, who would have braved the most virulent contagion to be near her. Most important of all, it allowed the mighty Alsop to apply for police help without fear of detection by the reporters and agents constantly swarming at headquarters.
When Garth entered the flat that afternoon, he was, unknowingly, already on the threshold of the strange case; for he had read in the noon editions the brief paragraph which recited an accident to all appearances common enough. A man had been picked up unconscious in the middle of a quiet street. Evidently he had been struck by an automobile. Two details, however, arrested Garth's attention. The victim, Ralph Brown, he knew as a successful private detective. Moreover, the outrage had occurred during the slack hours before the dawn. Apparently no clue as to its perpetrators remained. Garth spoke of that casually to the inspector. The huge, suffering man was scarcely intrigued. Wrapped in an ancient dressing-gown, his throat smothered beneath flannel, he sat in an easy chair, facing the fire, whose coals he perpetually reproved with a frown. He groaned. There was utter despair in the rumbling, animal-like note. Nora laughed.
"Laugh away," the inspector roared, "but make Garth forget he's a detective if he can't do better than hound a sick man with a cheap automobile case."
From her dark and striking face Nora's quiet eyes smiled sympathetically at Garth.
"These unimportant things, father, are sometimes the most important of all," she said. "Jim's right. It's odd no witnesses can be found."
As if there had been something prophetic in her words and her attitude, a muffled knock came from the outer door.
"Why doesn't he ring?" the inspector growled. "You haven't had the bell disconnected, Nora? Good Lord! Am I as sick as that?"
Nora, a trifle bewildered, moved towards the door. "Queer! And I think there are two in the hall."
Garth, as he always did, marveled at her acute perception. For, although he had heard no footsteps, no voices, two men followed Nora into the living room. The one in advance was young, with a frightened and apprehensive face. His companion was older and portlier, with narrow eyes and full-blooded cheeks. And those eyes were uneasy. For Garth they did not quite veil a sense of sheer terror. With a growing discomfort he guessed the cause of this visit.
Nora's voice betrayed none of the amazement Garth knew she felt.
