“Mr. Dunlap, stop a moment.” There was a look in the official’s eyes that froze Mr. Dunlap’s welcome on his lips and nailed him to the spot on which he stood. Chapman glanced at Burton, on whom O’Brien’s gaze was fastened. Burton had risen and stood trembling like an aspen leaf without a single shade of color left in cheeks or lips. Jack Dunlap’s face flushed somewhat indignantly as he rose and walked forward to the side of his kinsman. “With all due regard for that high respect I entertain for you, Mr. Dunlap, it has become my painful duty to enter your house tonight in my official capacity and arrest one accused of the most serious crime known to the law.” While O’Brien was speaking he moved toward the table, never removing his eyes from Burton. “What do you mean, sir?” cried Jack in a wrathful voice, interposing himself between O’Brien and the table. “Stand aside, Captain Dunlap!” said the Chief sternly. Quickly stepping to Burton’s side and placing his hand on his shoulder he said, “Walter Burton, I arrest you in the name of the Commonwealth, on the charge of murder.” With a movement too quick even for a glance to catch, the Chief jerked Burton’s hands together and snapped a pair of handcuffs on the wrists of the rapidly collapsing man. The eyes of all present were fixed, in stupified amazement, on O’Brien and Burton, and had not seen what stood in the open doorway until a low moan caused Jack to turn his head. He saw then the figure of Lucy slowly sinking to the floor. Lucy in her wanderings about the house was passing through the hall when the uniformed officer entered. Attracted by the unusual spectacle of a man in a blue coat ornamented with brass buttons, she had followed the policeman and overheard all that he had said, and seen what he had done. “I will furnish bail in any amount, O’Brien,” exclaimed Mr. Dunlap, staying the two officers by stepping before them as they almost carried Burton, unable to walk, from the room. “Please stand aside, Mr. Dunlap,” said the Chief kindly. “Don’t make it harder than it is now for me to do my duty,” and gently pushing the old gentleman aside, O’Brien and his assistant bore Burton from the library and the Dunlap mansion. “Help me, quick! Lucy has fainted!” called Jack, who, crippled as he was, could not raise the unconscious wife of Burton. When Mr. Dunlap reached Jack’s bending figure, Lucy opened her eyes, gazed about wildly for an instant, gasped for breath as if suffocating, and suddenly sprang unassisted to her feet, as if shot upward by some hidden mechanism. “Walter! My husband! Where is he? Where is grandfather? What has happened?” she cried out, in a confused way, as one just aroused from a sound sleep.
