“In those other cases of that night, the safe-blowing and theatre robbery, was there any unnecessary shooting?” Johnny asked.

“None reported. But then, of course, it is not likely that Mr. Hole-in-the-Hand was on the scene in either case. He was busy with you. If he was in on either of these, the work was done by his gang, not by him.”

That night a curious and startling thing happened. This affair, as Herman McCarthey agreed later, might or might not have a bearing on the problem just discussed.

The detective team of Drew and Howe worked for the most part during the daylight hours. They were assigned to the task of detecting and arresting pickpockets. If you rode a crowded street car, attended a league baseball game, or chanced to be on the edge of a crowd drawn together on the street corner by a vender of patent medicine or unbreakable combs, you might easily sight the nifty hat and flaming tie of Drew Lane, the natty detective. They knew more than three hundred pickpockets by sight, did this young pair. They picked up any of these on suspicion if they were found in a likely spot, and at once haled them into court.

This permanent assignment left Drew with his evenings free. Because of this, he and Johnny enjoyed many a night stroll together.

One of their favorite haunts was a slip which ended some four blocks from their shack, and extended for several blocks east until it lost itself in the waters of the lake. This narrow channel of water was lined on one side by great bulging, empty sheet iron sheds, and on the other by brick warehouses which appeared equally empty. A narrow landing extending the length of the sheds, and fast falling into decay, offered a precarious footing for any who chose to wander there.

It was a spooky place, this slip at night. At the end nearest the shore, half under water, half above, a one-time pleasure yacht lay rotting away. At the far end, an ancient tug fretted at a chain that was red with rust and from time to time added to the general melancholy of the place a hollow bub-bub as it bumped the shore.

One would scarcely say that a horde of gigantic red-eyed rats could add to the attractions or any place, let alone one such as this. Lend it a touch of joy, they did, nevertheless. This became Johnny’s hunting ground. Armed with his bow and quiver of arrows, he stalked rats as in other climes he had stalked wolves and bears.

Drew never tired of seeing his keen bladed arrow speed straight and true. There is a certain fascination about such expert marksmanship. Besides, Drew hated rats. He had said many times, “A great city has two scourges, professional criminals and rats. It’s every honest man’s duty to help rid the city of both.”

On this particular night Johnny and Drew had gone on one of their hunting trips. They had put out a lure of shelled corn during the day. Game was plentiful. In the half light of the smoke-dulled moon, many a rodent whose eyes gleamed in the dark met his death.
