His imagination quailed at the thought of a repetition of last night’s horrors.  He had been badly shaken by his collision with the table and even more so by the events that had followed it.  Those revolver shots still rang in his ears.

It was probably the memory of those shots that turned the scale.  It was unlikely he would again become entangled with a man bearing a tongue and the other things—­he had given up in despair the attempt to unravel the mystery of the tongue; it completely baffled him—­but it was by no means unlikely that if he spent another night in the gallery looking on the hall he might not again become a target for Lord Emsworth’s irresponsible firearm.  Nothing, in fact, was more likely; for in the disturbed state of the public mind the slightest sound after nightfall would be sufficient cause for a fusillade.

He had actually overheard young Algernon Wooster telling Lord Stockheath he had a jolly good mind to sit on the stairs that night with a shotgun, because it was his opinion that there was a jolly sight more in this business than there seemed to be; and what he thought of the bally affair was that there was a gang of some kind at work, and that that feller—­what’s-his-name?—­that feller Baxter was some sort of an accomplice.

With these things in his mind Baxter decided to remain that night in the security of his bedroom.  He had lost his nerve.  He formed this decision with the utmost reluctance, for the thought of leaving the road to the museum clear for marauders was bitter in the extreme.  If he could have overheard a conversation between Joan Valentine and Ashe Marson it is probable he would have risked Lord Emsworth’s revolver and the shotgun of the Honorable Algernon Wooster.

Ashe, when he met Joan and recounted the events of the night, at which Joan, who was a sound sleeper, had not been present, was inclined to blame himself as a failure.  True, fate had been against him, but the fact remained that he had achieved nothing.  Joan, however, was not of this opinion.

“You have done wonders,” she said.  “You have cleared the way for me.  That is my idea of real teamwork.  I’m so glad now that we formed our partnership.  It would have been too bad if I had got all the advantage of your work and had jumped in and deprived you of the reward.  As it is, I shall go down and finish the thing off to-night with a clear conscience.”

“You can’t mean that you dream of going down to the museum to-night!”

“Of course I do.”

“But it’s madness!”

“On the contrary, to-night is the one night when there ought to be no risk at all.”

“After what happened last night?”

“Because of what happened last night.  Do you imagine Mr. Baxter will dare to stir from his bed after that?  If ever there was a chance of getting this thing finished, it will be to-night.”

“You’re quite right.  I never looked at it in that way.  Baxter wouldn’t risk a second disaster.  I’ll certainly make a success of it this time.”
