I retraced my steps upstairs.  The Chinese ambassador, Vanhallon, and Lamartine were deep in conversation in the dead man’s sitting-room.  I was admitted to their confidence after a few minutes’ hesitation.  A draft for one hundred and sixty thousand pounds had been found upon the dead man, but notes to the value of forty thousand pounds were missing!  They looked at me a little curiously as I entered, and Lamartine explained the situation to me.

“We were wondering about the young lady,” he said.

“Then you need wonder no longer!” I said dryly.  “I give my word for it that she is ignorant altogether of this scheme.  She believed that her uncle was honestly attempting to carry out the plans for which his brother came to Europe, and as for searching for the money amongst her belongings, you might as well fly!”

“Where, then,” Vanhallon demanded, “has it gone to?  He has had so little time.”

I opened my lips and closed them.  After all, I had gained my end, and I had realized a little the folly of meddling with things which did not concern me.  So I held my peace.  I went and sat down by the side of my lady of the turquoises.

“Tell me,” I said, “how did you find him?—­and where?  Has he been ill, or what is it that is the matter?”

I moved my head towards where Delora was sitting.  The placid, child-like expression still remained with him.  The tragedy which had happened only a few yards away had left him unmoved.

“I heard all about him from Henri,” she said.  “The scheme originally was his.  Then they tried to hurry things through without us—­without my man Henri, of whom they had made use.  Henri came to London, and he died here!  That much I know.  How much more there is to be told, who can say?  But I said to myself, ‘I will be revenged!’ I knew the hospital to which he had been taken—­a private hospital from which few ever come out!  But I went there, and I swore that I was his daughter.  I frightened them all, for I knew that he had been drugged and poisoned till his brain had nearly given way.  They thought him harmless, and they let him come with me.  I brought him to England.  I brought him here.”

“And now?” I asked.

“Now I must go back,” she answered, “but at least Henri is avenged!”

She leaned towards me.

“Tell whoever takes care of him,” she whispered in my ear, “that he cannot live long.  The doctors have assured me.  It is a matter of weeks.”

I walked with her to the door.

“It was an expensive journey for you,” I remarked.

She laughed.

“Henri did leave me everything,” she said.  “I have no need of money.  If monsieur—­”

She sighed, and looked towards the door of Felicia’s room.  Then she fluttered away down the corridor, and I slowly retraced my steps.  Felicia came out in a few minutes and sat by her uncle’s side.  The others had all departed, and we were left alone.
