She was not surprised, then, to see a short iron bar in the professor’s hand. It was flattened and sharpened at one end.

By the light of the hand-lamp the man went to work on the locked desk. It was of heavy wood–no flimsy thing like that one which he had burst open so easily the day of the Widow Harrison’s vendue.

The man inserted the sharp end of the jimmy between the lid and the upper shelf of the desk. ’Phemie heard the woodwork crack, and this time she did not suppress a gasp.

Why! this fellow was actually breaking open the old doctor’s desk. Aunt Jane had not even sent them the keys of the desk and bookcases in this suite of rooms.

Then ’Phemie had a sudden thought. She was really afraid of the big man. She did not know what he might do to her if he found her here spying on his actions. And–she didn’t want the lock of the old desk smashed.

She reached up softly and turned with shaking fingers the old-fashioned wooden button that held shut the door of the case beside which she crouched.

She remembered very clearly that it had snapped open before when she was investigating–and with a little click. The door of this case acted almost as though the hinges had springs coiled in them.

At once, when she released the door, it swung open–and in yawning it did make a suspicious sound.

Professor Spink started–he had been about to bear down on the bar again. He flashed a look back over his shoulder. But the corner was shrouded in darkness.

’Phemie sighed–this time with intent. She remembered how she had been frightened so herself at her former visit to this office–and she believed the marauder now before her had been partially the cause of her fright.
