“Who’s there?” asked Eustace.

There was no answer.

“Mrs. Prince, is that you?”

“She is up above,” said Saunders; “I can hear her walking about the room.”

“Then lock the door; bolt it too.  Your move, Saunders.”

While Saunders sat with his eyes on the chessboard, Eustace walked over to the window and examined the fastenings.  He did the same in Saunders’s room and the bathroom.  There were no doors between the three rooms, or he would have shut and locked them too.

“Now, Saunders,” he said, “don’t stay all night over your move.  I’ve had time to smoke one cigarette already.  It’s bad to keep an invalid waiting.  There’s only one possible thing for you to do.  What was that?”

“The ivy blowing against the window.  There, it’s your move now, Eustace.”

“It wasn’t the ivy, you idiot.  It was someone tapping at the window,” and he pulled up the blind.  On the outer side of the window, clinging to the sash, was the hand.

“What is it that it’s holding?”

“It’s a pocket-knife.  It’s going to try to open the window by pushing back the fastener with the blade.”

“Well, let it try,” said Eustace.  “Those fasteners screw down; they can’t be opened that way.  Anyhow, we’ll close the shutters.  It’s your move, Saunders.  I’ve played.”

But Saunders found it impossible to fix his attention on the game.  He could not understand Eustace, who seemed all at once to have lost his fear.  “What do you say to some wine?” he asked.  “You seem to be taking things coolly, but I don’t mind confessing that I’m in a blessed funk.”

“You’ve no need to be.  There’s nothing supernatural about that hand, Saunders.  I mean it seems to be governed by the laws of time and space.  It’s not the sort of thing that vanishes into thin air or slides through oaken doors.  And since that’s so, I defy it to get in here.  We’ll leave the place in the morning.  I for one have bottomed the depths of fear.  Fill your glass, man!  The windows are all shuttered, the door is locked and bolted.  Pledge me my uncle Adrian!  Drink, man!  What are you waiting for?”

Saunders was standing with his glass half raised.  “It can get in,” he said hoarsely; “it can get in!  We’ve forgotten.  There’s the fireplace in my bedroom.  It will come down the chimney.”

“Quick!” said Eustace, as he rushed into the other room; “we haven’t a minute to lose.  What can we do?  Light the fire, Saunders.  Give me a match, quick!”

“They must be all in the other room.  I’ll get them.”

“Hurry, man, for goodness’ sake!  Look in the bookcase!  Look in the bathroom!  Here, come and stand here; I’ll look.”

“Be quick!” shouted Saunders.  “I can hear something!”

“Then plug a sheet from your bed up the chimney.  No, here’s a match.”  He had found one at last that had slipped into a crack in the floor.

“Is the fire laid?  Good, but it may not burn.  I know—­the oil from that old reading-lamp and this cotton-wool.  Now the match, quick!  Pull the sheet away, you fool!  We don’t want it now.”
