The next moment brought dismay to the watchers. "I think I'll deposit these elsewhere," observed Shaughnessy casually, with a glance toward the badgered Judge. "I don't think they're safe here." He slipped them into an inner pocket of his coat. Micky's blank stare of dismay was instantly succeeded by a sudden inspiration, a plan daring but desperate. He plucked at Slade's sleeve, drawing him away from the window. "He mustn't leave here with 'em," he whispered, and proceeded briefly to unfold his plan. Slade, who was of kin with O'Byrn in recklessness, was enthusiastic. "All right if they stay long enough," he muttered. "Let's take a look." A glance through the glass showed the two occupants of the office, with chairs close together, conversing in low tones. Shaughnessy was evidently elaborating his programme. "You stay here and keep watch," whispered Slade. "I can get over and back quick. There's a drug store two blocks away, and I've got an awful toothache," with a nudge. "Matches? No, I can get around here like a cat, and as still." He glided silently away. Micky resumed his watch at the office door. The moments dragged by slowly. Micky grew impatient. What if Slade should return too late? And now the Judge was rising, donning his coat and hat. Shaughnessy was seeing him to the door; it opened--he was gone. Micky strained his ears, no sounds of a returning Slade. Shaughnessy walked leisurely to his desk. Ah! it was all right, he was going to sit down. But no, he closed the lid of his desk; donned his hat, took down his coat from the hook, was leisurely getting into it. Then Micky with difficulty repressed a startled cry. Out of nowhere, without a sound in the intense stillness, Slade materialized from darkness at his side. "Quick!" gasped Micky, "he's going!" But for Slade's restraining hand he would have thrown himself bodily against the door. "Hold on! do you want him to see us?" he whispered savagely. "Here! quick, put this on." He thrust an object into Micky's hand. "It's a mask," he explained, adjusting one of his own. "Gettin' 'em is what kept me." The masks were of the grotesque little variety affected alike by house breakers and masqueraders. Micky learned afterward that Slade had a dubious friend in the vicinity who possessed such conveniences. After leaving the office he had bethought himself of the awkwardness of Shaughnessy's recognizing them in the prospective encounter. Slade had a long head. The plotters took another look at the interior. Shaughnessy was standing with his back to them, leisurely selecting a cigar from his case, preparatory to going. "Now for it!" whispered Slade, and the two, looking like two simon-pure burglars, crept forward. Slade's hand fell upon the handle of the office door. Contrary to his expectations, it was unlocked. He nudged Micky, immediately behind, to impose caution, and softly opened the door.
