“You see—­you never know what a woman will do,” he continued.

Miss Cornelia smiled.  She broke open the revolver, five loaded shells fell from it to the floor.  The Bat stared at her—­then stared incredulously at the bullets.

“You see,” she said, “I, too, have a little imagination!”

CHAPTER TWENTY-ONE

QUITE A COLLECTION

An hour or so later in a living-room whose terrors had departed, Miss Cornelia, her niece, and Jack Bailey were gathered before a roaring fire.  The local police had come and gone; the bodies of Courtleigh Fleming and his nephew had been removed to the mortuary; Beresford had returned to his home, though under summons as a material witness; the Bat, under heavy guard, had gone off under charge of the detective.  As for Doctor Wells, he too was under arrest, and a broken man, though, considering the fact that Courtleigh Fleming had been throughout the prime mover in the conspiracy, he might escape with a comparatively light sentence.  In a little while the newspapermen of all the great journals would be at the door—­but for a moment the sorely tried group at Cedarcrest enjoyed a temporary respite and they made the best of it while they could.

The fire burned brightly and the lovers, hand in hand, sat before it.  But Miss Cornelia, birdlike and brisk, sat upright on a chair near by and relived the greatest triumph of her life while she knitted with automatic precision.

“Knit two, purl two,” she would say, and then would wander once more back to the subject in hand.  Out behind the flower garden the ruins of the garage and her beloved car were still smoldering; a cool night wind came through the broken windowpane where not so long before the bloody hand of the injured detective had intruded itself.  On the door to the hall, still fastened as the Bat had left it, was the pathetic little creature with which the Bat had signed a job—­for once, before he had completed it.

But calmly and dispassionately Miss Cornelia worked out the crossword puzzle of the evening and announced her results.

“It is all clear,” she said.  “Of course the Doctor had the blue-print.  And the Bat tried to get it from him.  Then when the Doctor had stunned him and locked him in the billiard room, the Bat still had the key and unlocked his own handcuffs.  After that he had only to get out of a window and shut us in here.”

And again: 

“He had probably trailed the real detective all the way from town and attacked him where Mr. Beresford found the watch.”

Once, too, she harkened back to the anonymous letters—­

“It must have been a blow to the Doctor and Courtleigh Fleming when they found me settled in the house!” She smiled grimly.  “And when their letters failed to dislodge me.”

But it was the Bat who held her interest; his daring assumption of the detective’s identity, his searching of the house ostensibly for their safety but in reality for the treasure, and that one moment of irresolution when he did not shoot the Doctor at the top of the ladder.  And thereafter lost his chance—­
