The first thing his friend told him was that he was to join a scientific expedition to the Congo, and that his party would follow almost exactly the same route that had been taken by the Stanley Expedition when it set out to look for Emin Pascha.

Benda wrote: “This letter then, my dear friend, is written to say good-bye for a number of years, perhaps forever. I feel as if I had been born anew. I have eyes again; and the ideas that fill my brain are no longer condemned to be stifled in the morass of imprisoned colleagues, loyal and inimical. To labour in nature’s laboratory will make me forget the wrongs I have suffered, the injustice that has been done me. Hunger and thirst, disease and danger will of course have to be endured; they are the effects of those crimes of civilisation that spare the body while they poison the mind and soul.”

Further on Benda wrote: “I am bound to my home by only two people, my mother and you. When I think of you, a feeling of pride comes over me; every hour we spent together is indelibly stamped on my heart. But there is one delicate point: it is a point of conscience. Call it, so far as I am concerned, a chip; call it anything you please. The fact is I have had a Don Quixotic run in, and I have got to defend myself.”

Daniel shook his head and read on. Benda knew nothing of his marriage. He did not even seem to know that Daniel and Gertrude had been engaged. Or if he had known it he had forgotten it. Daniel could hardly believe his own eyes when he came to the following passage: “My greatest anxiety always lay in the fear that you would pass Eleanore by. I was too cowardly to tell you how I felt on this point, and I have reproached myself ever since for my cowardice. Now that I am leaving I tell you how I feel about this matter, though not exactly with the sensation of performing a belated task.”

For Heaven’s sake, thought Daniel, what is he trying to do to me?

“I have often thought about it in quiet hours; it gave me the same feeling of satisfaction that I have in a chemical experiment, when the reactions of the various elements take place as they should: what Eleanore says is your word; what you feel is Eleanore’s law.”

He is seeing ghosts, cried Daniel, he is tangling up the threads of my life. What does he mean? Why does he do it?

“Don’t neglect what I am telling you! Don’t crush that wonderful flower! The girl is a rare specimen; the rarest I know. You need your whole heart with all its powers of love and kindness to appreciate her. But if my words reach you too late, please tear this letter into shreds, and get the whole idea out of your mind as soon and completely as possible.”

“Come, let’s eat,” said Gertrude, as she entered the room with a dish of pickled herring.

Eleanore was sitting on the sofa looking at Daniel quizzically. He was lost in thought.
