Meanwhile Locke, his lungs almost bursting and the blood surging to his head, had managed to free himself from his shackles and had floated to the surface of the water. As he came up he swam to the piles of the dock just as several boatmen saw him and hurried to his aid.
They heard the screams of Eva, and all started running up the dock, but not in time to capture the Automaton, who, warned by the emissaries, crashed through the side of the dock house nearest the shore and escaped.
A moment later Locke, searching through the piles of boxes, bales, and crates, found Eva, just recovering from her fright, and in the joy of having saved her by his timely return forgot, for the moment, to pursue the terrible villain, who managed to reach a waiting closed car and was whisked away.
Thus it was that after their return to Brent Rock, on the following day Eva was ministering to her father, still hopelessly insane through the failure to discover the antidote to the madness.
While Eva was engaged in her ministrations up-stairs Locke was finishing some experiment in his laboratory. Down-stairs, Balcom had just arrived in the hall, where he was met by Zita with a report of what had happened the day before.
"Tell it to me in the strong-room while I place this package there," Balcom whispered, indicating the package which he had brought.
Together Balcom and Zita descended to the cellar and made their way to the Graveyard of Genius as Zita poured forth her story, unmindful of the fact that the butler had seen them go down and was watching very skeptically. In the Graveyard Balcom unwrapped a small model of a motor and placed it on the shelf.
Eva, having left her father, came upon Locke in the hall, and there they stood talking for a moment, when the butler approached apologetically.
"Begging your pardon, Miss Brent," he reported, "but I just saw Mr. Balcom go down to the strong-room with Miss Zita, and I thought you might like to know."
"Thank you," nodded Eva, dismissing the butler and trying to show no concern in the matter.
But Locke shot a quick glance at her as the servant left, and it was evident that both felt the same suspicion, for Locke immediately excused himself and hurried down-stairs.
