Lets say,
Feige is not Marut. Esperanza is too blonde to be either Murga's child or Elena's. No one knows when Esperanza was born. Esperanza looks like Feige.
In 1905 Feige left home. A few months later a girl named Elsa shows up at Feige's parents house. She wants to marry Feige. A month or so later, she leaves. That much is in Wyatt's book, now we speculate. The girl is pregnant. She returns to Feige. But Feige has already made plans to go to Mexico. She follows him. She gives birth in Mexico in 1905 or 1906.. She dies in childbirth. Feige, the sailor, is gone. The orphan is adopted by the Lopez Mateos family. They name her Esperanza. When Mariano is killed, or dies, Elena is overwhelmed and sends Esperanza to her friend and lover, the father of one of her sons, Gonzalo de Murga, owner of a sugar plantation in the isthmus of Tehuantepec. Murga buys his plantation and moves to Oaxaca about the same time Mariano dies. Murga takes Esperanza with him. Later Elena retrieves Esperanza. Esperanza, Figueroa and Henry all believe Esperanza was not the natural daughter of Elena.
Figueroa says Esperanza is adopted by Elena, she is the daughter of Murga and an Englishwoman. Regina Santiago says there never was an Englishwoman, and Murga's wife, who left Mexico about the time Esperanza was born, never had a girl. Henry says Esperanza is the daughter of Traven and an Englishwoman.
Feige returns to Mexico. His wife is dead, his daughter lost. He plunges into Mexican life. He is the one Mexican subscriber to Marut's Brickburner. When Marut is in jail, he knows he can give the British police Feige's name. On leaving England, Marut makes for Mexico where Feige is expecting him. He calls him B. B. has rented a cabin in Columbia, just north of Tampico. B. has lived in Mexico and the United States. He has written stories. He is not a professional writer. He has been there, he saw it. Marut calls him B. in his diary, and they live together. B. says to Marut, I have been expecting you. B. is the guy. We just have to figure out who B. is. Irene Mermet knows both of them.
Croves owed something to Esperanza's father. There was no reason to pluck her from obscurity and put her on the literary map. There was no reason to make up such a colossal lie as to being her father unless there were some past history.
Or,
Marut was not Feige. Feige is not important. Marut shows up in Germany about the time Esperanza was born in Mexico. This is a known fact. His first appearance as Ret Marut is around 1907 (Wyatt p323). Ret Marut always said he was an American. Baumann says there are Americanisms in Ret Marut's brickburner writings. Ret Marut applies for German citizenship around 1915. This is a man who was supposedly in the German army in 1904. This fact even puzzles Wyatt, who "solved" the mystery. What if Marut, the sailor, marries Esperanza's British mother in Mexico, leaves, and the mother dies in childbirth. The child is taken by Lopez Mateos. In 1924, Marut comes back, and nearly all of Henry's story turns out to be true. It also answers many of those nagging problems with the conventional history. When was he a sailor? On the one-way trip to Mexico? Why was he so obsessed with being a bastard, if his parents married a month after he was born? Why does the locksmith never enter his stories? Croves is said to have admitted being Marut, but never Feige. He was his own American Erlebnistrager. He wrote it all. Its just that 1924 was the second time he had been to Mexico.
