“As to where they have gone,” continued Bickley, taking no notice of Bastin, “I really don’t know.  My expectation is, however, that when we go to look tomorrow morning—­and I suggest that we should not do so before then in order that we may give our minds time to clear—­we shall find that sepulchre place quite empty, even perhaps without the crystal coffins we have imagined to stand there.”

“Perhaps we shall find that there isn’t a cave at all and that we are not sitting on a flat rock outside of it,” suggested Bastin with heavy sarcasm, adding, “You are clever in your way, Bickley, but you can talk more rubbish than any man I ever knew.”

“They told us they would come back tonight or tomorrow,” I said.  “If they do, what will you say then, Bickley?”

“I will wait till they come to answer that question.  Now let us go for a walk and try to change our thoughts.  We are all over-strained and scarcely know what we are saying.”

“One more question,” I said as we rose to start.  “Did Tommy suffer from hallucinations as well as ourselves?”

“Why not?” answered Bickley.  “He is an animal just as we are, or perhaps we thought we saw Tommy do the things he did.”

“When you found that basket of fruit, Bastin, which the natives brought over in the canoe, was there a bough covered with red flowers lying on the top of it?”

“Yes, Arbuthnot, one bough only; I threw it down on the rock as it got in the way when I was carrying the basket.”

“Which flowering bough we all thought we saw the Sleeper Oro carry away after Tommy had brought it to him.”

“Yes; he made me pick it up and give it to him,” said Bastin.

“Well, if we did not see this it should still be lying on the rock, as there has been no wind and there are no animals here to carry it away.  You will admit that, Bickley?”

He nodded.

“Then if it has gone you will admit also that the presumption is that we saw what we thought we did see?”

“I do not know how that conclusion can be avoided, at any rate so far as the incident of the bough is concerned,” replied Bickley with caution.

Then, without more words, we started to look.  At the spot where the bough should have been, there was no bough, but on the rock lay several of the red flowers, bitten off, I suppose, by Tommy while he was carrying it.  Nor was this all.  I think I have mentioned that the Glittering Lady wore sandals which were fastened with red studs that looked like rubies or carbuncles.  On the rock lay one of these studs.  I picked it up and we examined it.  It had been sewn to the sandal-strap with golden thread or silk.  Some of this substance hung from the hole drilled in the stone which served for an eye.  It was as rotten as tinder, apparently with extreme age.  Moreover, the hard gem itself was pitted as though the passage of time had taken effect upon it, though this may have been caused by other agencies, such as the action of the radium rays.  I smiled at Bickley who looked disconcerted and even sad.  In a way it is painful to see the effect upon an able and earnest man of the upsetting of his lifelong theories.
