Suddenly and unreasonably Gard choked with fear. In one bound he crossed the room and stood staring down at the face of his host. For an instant he stood paralyzed with amazement and horror. Then, as always, when in the heart of the tempest, he became calm, and his mind, as if acting under some heroic stimulant, became intensely clarified. Mahr was dead. He leaned forward and lifted the head; the body was still warm, and it fell forward, limp and heavy. On the left temple was a large contusion and a slight cut. The cause was not far to seek. On the table lay an ancient flintlock pistol, somewhat apart from a heap of small arms belonging to an eighteenth century trophy.
Murder! Murder--and Mrs. Marteen! His imagination pictured her beautiful still face suddenly becoming maniacal with fury and pain. Gard suppressed an exclamation. Well, he would swear Mahr was alive at half after eleven, when he had seen him. If anyone knew of her coming before that, she would be cleared. No one knew of his own feud with Mahr; no one suspected it. His word would be accepted.
Mahr's face, repulsive in life, was hideous in death--a mask of selfishness, duplicity and venomous cunning from which departing life had taken its one charm of intelligence. He looked at the wound again. The blow must have been sudden and of great force. Acting on an impulse, he tiptoed to one of the curtained windows, unlocked the fastening and raised it slightly. A robbery--why not? Silently moving back into the room, he approached the corpse and with nervous rapidity looted the dead man of everything of value, leaving the torn wallet, a wornout crumpled affair, lying on the floor. He opened and emptied the table drawers, as if a hurried search had been made. Slipping the compromising jewels into his overcoat pocket, he turned about and faced the room like a stage manager judging of a play's setting. The luxurious furnishings, the long mahogany table warmly reflecting the lights of the heavily shaded lamp; the wide, gaping fireplace; the lurking shadows of the corners; the curtain by the opened window bellying slightly in the draught; above, in the soft radiance of the hooded electrics, the glowing, living, radiant personality of the Vandyke; below, the stark, evil face of the dead, with its blue bruised temple and blood-clotted hair.
Gard strove to reconstruct the crime as the next entrant would judge it--the thief gliding in by the window; the collector busy over the examination of his curios; the blow, probably only intended to stun; the hasty theft and stealthy exit.
His heart pounded in his breast, but it was with outward calm that he crossed the threshold, calling back a "Good-night," whose grim irony was not lost upon him. In the hall, as he put on his hat, he addressed the servant casually:
"Mr. Mahr says you may lock up and go. He does not want to be disturbed, as he has some papers that will keep him late. Remind Mr. Mahr to call me at the New Willard in the morning; I may have some news."
As he left the house he staggered; he felt his knees shaking. With a superhuman effort he steadied himself--Denning must not suspect anything unusual. He descended the steps with a firm tread, and pausing at the last step, twisted as if to reach an uncomfortably settled coat collar--his quick glance taking in the contour of the house and the probability of access by the window. The glimpse was reassuring. By means of the iron railing a man might readily gain the ledge below the first floor windows. He entered the limousine and nodded to Denning.
"All right," he said. "On to Washington."
