While Del Mar was speaking, Elaine picked up a ribbon from the table and started to tie it about Rusty's neck. As Del Mar proceeded she paused, still holding the ribbon. Rusty, who hated ribbons, saw his chance and quietly sidled out, seeking refuge in the conservatory.

Alone in the conservatory, Rusty quickly forgot about the ribbon and began nosing about the palms. At last he came to the pot in which the torpedo model had been buried in the soft earth by the thief the night it had been stolen from the fountain.

Quickly Elaine recalled herself and, seeing the ribbon in her hand and Rusty gone, called him. There was no answer, and she excused herself, for it was against the rules for Rusty to wander about.

In his haste the thief had left just a corner of the handkerchief sticking out of the dirt. What none of us had noticed, Rusty's keen eyes and nose discovered and his instinct told him to dig for it. In a moment he uncovered the torpedo and handkerchief and sniffed.

Just then he heard his mistress calling him. Rusty had been whipped for digging in the conservatory and now, with his tail between his legs, he seized the torpedo in his mouth and bolted for the door of the drawing-room, for he had heard voices in the library. As he did so he dropped the handkerchief and the little propeller, loosened by his teeth, fell off.

Elaine entered the conservatory, still calling. Rusty was not there. He had reached the stairs, scurrying up to the attic, still holding the torpedo model in his mouth. He pushed open the attic door and ran in.

Rusty's last refuge in time of trouble was back of a number of trunks, among which were two of almost the same size and appearance. Behind one of them, he had hidden a miscellaneous collection of bones, pieces of biscuit and things dear to his heart. He dropped the torpedo among these treasures.

Del Mar, meanwhile, had followed Elaine through the hall and into the conservatory. As he entered he could see her stooping down to look through the palms for Rusty. She straightened up and went on out.

Del Mar followed. Beside the palm pot where Rusty had found the torpedo, he happened to see the old handkerchief soiled with dirt.

Near-by lay the little propeller. He picked them up.

"She has found it!" he exclaimed in wonder, following Elaine.

By this time Rusty had responded to Elaine's calls and came tearing down-stairs again.

"Naughty Rusty," chided Elaine, tying the ribbon on him.

"So--you have found him at last?" remarked Del Mar looking quickly at Elaine to see if she would get a double meaning.

"Yes. He's had a fine time running away," she replied.

Del Mar was scarcely able to conceal his suspicion of her. Was she a clever actress, hiding her discovery, he wondered?

Outside, on the lawn, Del Mar's men had been looking about, but had discovered nothing. They paused a moment to speak.

"Look out!" whispered one of them. "There's some one coming."

They dropped down in the shadow. There in the light of the street lamps was the fussy old gentleman coming across the lawn. He stole up to the door of the conservatory and looked through. Del Mar's men crawled a few feet closer. The little old man entered the conservatory and looked about again stealthily. The two men followed him in noiselessly and watched as he bent over the palm pot from which the dog had dug up the torpedo. He looked at the hole curiously. Just then he heard sounds behind him and sprang to his feet.

"Hands up!" ordered one of the men covering him with a gun.

The little old man threw up his hands, raising his cane still in his right hand. The man with the gun took a step closer. As he did so, the little old man brought down his cane with a quick blow and knocked the gun out of his hand. The second man seized the cane. The old man jerked the cane back and was standing there with a thin tough steel rapier. It was a sword-cane. Del Mar's man held the sheath.

As the man attacked with the sheath, the little old man parried, sent it flying from his grasp, and wounded him. The wounded man sank down, while the little old man ran off through the palms, followed by the other of Del Mar's men.

Around the hall, he ran, and back into the conservatory where he picked up a heavy chair and threw it through the gla.s.s, dropping himself behind a convenient hiding-place near-by. Del Mar's man, close after him, mistaking the crash of gla.s.s for the escape of the man he was pursuing, went on through the broken exit. Then the little old man doubled on his tracks and made for the front of the house.

With Aunt Josephine I had remained in the library.

"What's that?" I exclaimed at the first sounds. "A fight?"

Together we rushed for the conservatory.

The fight followed so quickly by the crash of gla.s.s also alarmed Elaine and Del Mar in the hallway and they hurried toward the library, which we had just left, by another door.

As they entered, they saw a little old gentleman rushing in from the conservatory and locking the door behind him. He whirled about, and he and Del Mar recognized each other at once. They drew guns together, but the little old man fired first.

His bullet struck the wall back of Del Mar and a cloud of vapor was instantly formed, enveloping Del Mar and even Elaine. Del Mar fell, overcome, while Elaine sank more slowly. The little old man ran forward.

In the conservatory, Aunt Josephine and I heard the shooting, just as one of Del Mar's men ran in again. With him we ran back toward the library.

By this time the whole house was aroused. Jennings and Marie were hurrying down-stairs, crying for help and making their way to the library also.

In the library, the little old man bent over Del Mar and Elaine. But it was only a moment later that he heard the whole house aroused. Quickly he shut and locked the folding-doors to the drawing-room, as, with Del Mar's man, I was beating at the rear library door.

"I'll go around," I suggested, hurrying off, while Del Mar's man tried to beat in the door.

Inside the little old man who had been listening saw that there was no means of escape. He pulled off his coat and vest and turned them inside out. On the inside he had prepared an exact copy of Jennings' livery.

It was only a matter of seconds before he had completed his change. For a moment he paused and looked at the two prostrate figures before him.

Then he took a rose from a vase on the table and placed it in Elaine's hand.

Finally, with his whiskers and wig off he moved to the rear door where Del Mar's man was beating and opened it.

"Look," he cried pointing in an agitated way at Del Mar and Elaine.

"What shall we do?"

Del Mar's man, who had never seen Jennings, ran to his master and the little old man, in his new disguise, slipped quietly into the hall and out the front door, where he had a taxicab waiting for him, down the street.

A moment later I burst open the other library door and Aunt Josephine followed me in, just as Jennings himself and Marie entered from the drawing-room.

It was only a moment before we had Del Mar, who was most in need of care, on the sofa and Elaine, already regaining consciousness, lay back in a deep easy chair.

As Del Mar moved, I turned again to Elaine who was now nearly recovered.

"How do you feel?" I asked anxiously.

Her throat was parched by the asphyxiating fumes, but she smiled brightly, though weakly.

"Wh-where did I get that?" she managed to gasp finally, catching sight of the rose in her hand. "Did you put it there?"

I shook my head and she gazed at the rose, wondering.

Whoever the little man was, he was gone.

I longed for Craig.
