Suddenly we heard shouts on the other side of the wall, as though some one were attacking some one else.

There seemed to be several of them, for a man quickly flung himself over the wall and ran to us.

“They’re after us,” he shouted to Bailey.

Instantly our visitor drew a gun and followed the newcomer as he ran to get out of the garden in the opposite direction.

Just then a tall, well-dressed, striking man came over the wall, accompanied by another dressed as a policeman, and rushed toward us.

. . . . . . .

The car bearing the mysterious stranger, Del Mar, kept on until it reached New York, then made its way through the city until it came to the Hotel La Coste.

Del Mar jumped out of the car, his wet clothes covered completely by the long coat.  He registered and rode up in the elevator to rooms which had already been engaged for him.  In his suite a valet was already unpacking some trunks and laying out clothes when Del Mar and his assistant entered.

With an exclamation of satisfaction at his unostentatious entry into the city, Del Mar threw off his heavy coat.  The valet hastened to assist him in removing the clothes still wet and wrinkled from his plunge into the sea.

Scarcely had Del Mar changed his clothes than he received two visitors.  Strangely enough they were men dressed in the uniform of policemen.

“First of all we must convince them of our honesty,” he said looking fixedly at the two men.  “Orders have been given to the men employed by Wu Fang to be about in half an hour.  We must pretend to arrest them on sight.  You understand?”

“Yes, sir,” they nodded.

“Very well, come on,” Del Mar ordered taking up his hat and preceding them from the room.

Outside the La Coste, Del Mar and his two policemen entered the car which had driven Del Mar from the sea coast and were quickly whisked away, up-town, until they came near the Dodge house.

Del Mar leaped from the car followed by his two policemen.  “There they are, already,” he whispered, pointing up the avenue.

All three hastened up the avenue now where, beside a wall, they could see two men looking through intently as though very angry at something going on inside.

“Arrest them!” shouted Del Mar as his own men ran forward.

The fight was short and sharp, with every evidence of being genuine.  One of the men managed to break away and jump the garden wall, with Del Mar and one of the policemen after him, while the other only reached the wall to be dragged down by the other policeman.

Elaine and I had been, as I have said, talking with the man named Bailey who posed as a Secret Service man, when the rumpus began.  As the man came over the fence, warning Bailey, it was evident that neither of them had time to escape.  With his club the policeman struck the newcomer of the two flat while the tall, athletic gentleman leaped upon Bailey and before we knew it had him disarmed.  In a most clean-cut and professional way he snapped the bracelets on the man.
