"You don't think I know anything about that money?" she said, a little wildly, hoping that a display of sham anger might throw him off the trail he seemed to be following.

He seemed to accept her words, cynically, at their face value.

"No," he said, "but you know somebody who does." Dale hesitated, sought for a biting retort, found none. It did not matter; any respite, no matter how momentary, from these probing questions, would be a relief. She silently took one of the lighted candles and left the living-room to search for her aunt.

Left alone, the detective reflected for a moment, then picking up the one lighted candle that remained, commenced a systematic examination of the living-room. His methods were thorough, but if, when he came to the end of his quest, he had made any new discoveries, the reticent composure of his face did not betray the fact. When he had finished he turned patiently toward the billiard room--the little flame of his candle was swallowed up in its dark recesses--he closed the door of the living-room behind him. The storm was dying away now, but a few flashes of lightning still flickered, lighting up the darkness of the deserted living-room now and then with a harsh, brief glare.

A lightning flash--a shadow cast abruptly on the shade of one of the French windows, to disappear as abruptly as the flash was blotted out--the shadow of a man--a prowler--feeling his way through the lightning-slashed darkness to the terrace door. The detective? Brooks? The Bat? The lightning flash was too brief for any observer to have recognized the stealing shape--if any observer had been there.

But the lack of an observer was promptly remedied. Just as the shadowy shape reached the terrace door and its shadow-fingers closed over the knob, Lizzie entered the deserted living-room on stumbling feet. She was carrying a tray of dishes and food--some cold meat on a platter, a cup and saucer, a roll, a butter pat--and she walked slowly, with terror only one leap behind her and blank darkness ahead.

She had only reached the table and was preparing to deposit her tray and beat a shameful retreat, when a sound behind her made her turn. The key in the door from the terrace to the alcove had clicked. Paralyzed with fright she stared and waited, and the next moment a formless thing, a blacker shadow in a world of shadows, passed swiftly in and up the small staircase.

But not only a shadow. To Lizzie's terrified eyes it bore an eye, a single gleaming eye, just above the level of the stair rail, and this eye was turned on her.
