At the foot of the down-at-heel side street, Herc could catch a glimpse of water and could sight the barn-like outlines of some of the deserted factories already referred to.

"Where in the world can they be bound?" he found himself wondering.

Could he have known the events of the last twelve hours, he would also have wondered at their being there at all. It is not given to everyone to come as close to the grim scythe of death and to escape scot-free as Saki and Kenworth had done.

As it happened, Herc was not destined to have to wait long before his curiosity was, at least in part, gratified. The two men came to an abrupt halt in front of a store that was even more dingy in appearance than its neighbors. Grass was sprouting through the cracks in the rickety wooden sidewalk in front of it, and, so far as Herc could see, from the distance he was obliged to keep, the establishment bore no outward and visible sign of the goods for sale within. Yet its big, dirty window showed that it was a store of some sort.

Herc dodged into a doorway as the two men came to a standstill in front of this place. By peeping cautiously out he was able to ascertain that they had apparently reached their destination. At any rate, he saw Saki step up to the door and open it.

Then the portal swallowed them both, and Herc was left alone on the solitary by-street.

"Umph, what's the next move?" he muttered to himself. "Looks like it's up to me to do something, but I'll be keel-hauled if I can think right now just what that 'something' is."

He paused irresolute. Then suddenly he came to action. He had decided to cross the street and reconnoiter from there, where he could obtain a view of the place the two men he was tracking had entered.

The maneuver did not take long, and was accomplished so far as the lad could see, without his being detected, or indeed the slightest notice being taken of him. So far, so good. Herc gazed across the street at the forlorn-looking place the two men had entered.
