“As to the man’s identity,” said Professor Challenger, “I have no doubt whatever upon that point. As I made my way up the river before I reached you at the fazenda I instituted very particular inquiries about Maple White. At Pará they knew nothing. Fortunately, I had a definite clue, for there was a particular picture in his sketchbook which showed him taking lunch with a certain ecclesiastic at Rosario. This priest I was able to find, and though he proved a very argumentative fellow, who took it absurdly amiss that I should point out to him the corrosive effect which modern science must have upon his beliefs, he none the less gave me some positive information. Maple White passed Rosario four years ago, or two years before I saw his dead body. He was not alone at the time, but there was a friend, an American named James Colver, who remained in the boat and did not meet this ecclesiastic. I think, therefore, that there can be no doubt that we are now looking upon the remains of this James Colver.”
