Dundee tried to recapture the picture of the stampede which had followed upon his permission for all guests to go to their homes. But it was useless. He had stayed in the living room with Strawn, had taken not the slightest interest in the scramble for hats, coats and sticks. For Strawn had previously assured him that the guest closet had been thoroughly searched.
So quickly that he felt slightly dizzy, Dundee's thoughts raced around the new discovery. This changed everything, of course. Any one of half a dozen persons could have arrived with the gun and silencer—not screwed together, of course, because of the ungainly length—and seized the opportunity presented by Nita's being alone in her bedroom to shoot her. What easier, then, than to hide the weapon on this secret shelf, the "door" of which yielded to the slightest pressure? And what easier than to retrieve the weapon after permission had been granted to all to return to their homes? Easy enough to manage to go alone to the closet for a hat, the extra minute of time unnoticed in the general excitement. It had been vitally necessary, too, to retrieve the weapon, since any innocent member of that party might have remembered later to mention the secret hiding place to the police—secret no longer since Judge Marshall had gossiped about it....
Then another thought boiled up and demanded attention. In the new theory, what place did the "bang or bump" have—that noise which Flora Miles, concealed in Nita's closet, had dimly heard? Dundee had been positive, when Lydia had discovered the shattered electric bulb in the big bronze lamp that its position in Nita's room indicated the progress of the flight of the murderer—flight diagonally across the room toward the back hall. But now—
A little dashed, Dundee returned to the bedroom. The big lamp was where he had first seen it—about a foot beyond the window nearest the porch, and at the head of the chaise longue which was set between the two west windows, where, according to Lydia, the lamp always stood. The too-long cord lay slackly along the floor near the west wall, and extended to the double outlet on the baseboard behind the bookcase.... A slack cord!
Down on his hands and knees Dundee went, to peer under the low bottom shelf of the bookcase.... Yes! The pronged plug of the lamp cord had been jerked almost out of the baseboard outlet! It was easy to visualize what had happened: The murderer, after firing the shot, had involuntarily taken a step or even several steps backward, until his foot had caught in the loop of electric cord, causing the big lamp to be thrown violently against the wall near which it stood.... But who?
Any one of half a dozen people! But—who?
CHAPTER NINETEEN
Having ticketed the big bronze lamp, which he had brought with him from the Selim house, and locked it away in the room devoted to "exhibits for the state," Bonnie Dundee hurried into Penny's office, primed with the news of his discovery of the secret hiding place and eager to lay his new theory before the district attorney.
"Bill's gone," Penny interrupted her swift typing to inform him. "To Chicago. He had only fifteen minutes to make the three o'clock train, after he received a wire saying his mother is not expected to live. He tried to reach you at the Selim house, but one of Captain Strawn's men said you had left."
