Rhoda Gray had paused in almost hopeless indecision as to how or where to begin her search, when the Sparrow spoke again.

“It looks like we got a long hunt,” whispered the Sparrow; “but a few minutes before you came, a guy with a lantern comes from over across the yard there and nosed around that shed, and acted kind of queer, and I could see him stick his head up against them side doors there as though he was listenin' for something inside. Does that wise you up to anything?”

“Yes!” she breathed tensely. “That was the watchman. He's one of them. The man we want is in that shed beyond a doubt. Hurry, Marty—hurry!”

They ran together now, and reached the double side-door. It was evidently for freight purposes only, and probably barred on the inside, for they found there was no way of opening it from without.

“There must be an entrance,” she said feverishly—and led the way toward the front of the building in the direction away from the river. “Yes, here it is!” she exclaimed, as they rounded the end of the shed.

She tried the door. It was locked. She felt in her pocket for her skeleton keys, for she had not been unprepared for just such an emergency, but the Sparrow brushed her aside.

“Leave it to me!” he said quickly. “I'll pick that lock like one o'clock! It won't take me more'n a minute.”

Rhoda Gray did not stand and watch him. Minutes were priceless things, and she could put the minute he asked for to better advantage than by idling it away. With an added injunction to hurry and that she would be back in an instant, she was already racing around the opposite side of the shed. If they were pressed, cornered, by the arrival of Danglar, it might well mean the difference between life and death to all of them if she had an intimate knowledge of the surroundings.

She was running at top speed. Halfway down the length of the shed she tripped and fell over some object. She pushed it aside as she rose. It was an old iron casting, more bulky in shape than in weight, though she found it none too light to lift comfortably. She ran on. A wharf projected out, she found, from this end of the shed. At the edge, she peered over. It was quite light here again; away from the protecting shadows of the shed, the rays of the arc lamp played without hindrance on the wharf just as they did on the shed's side door. Below, some ten or twelve feet below, and at the corner of the wharf, a boat, or, rather, a sort of scow, for it was larger than a boat though oars lay along its thwarts, was moored. It was partly decked over, and she could see a small black opening into the forward end of it, though the opening itself was almost hidden by a heap of tarpaulin, or sailcloth, or something of the kind, that lay in the bottom of the craft. She nodded her head. They might all of them use that boat to advantage!

Rhoda Gray turned and ran back. The Sparrow, with a grunt of satisfaction, was just opening the door. She stepped through the doorway. The Sparrow followed.
