not possibly have done wrong.

However his friends might rage, and however her people might
wonder and seek to pry into the secret, no satisfaction was given
on either side. The abandoned wife never uttered a word of
explanation. Houston was equally reticent and self-controlled. In
later years he sometimes drank deeply and was loose-tongued; but
never, even in his cups, could he be persuaded to say a single
word about his wife.

The whole thing is a mystery and cannot be solved by any evidence
that we have. Almost every one who has written of it seems to have
indulged in mere guesswork. One popular theory is that Miss Allen
was in love with some one else; that her parents forced her into a
brilliant marriage with Houston, which, however, she could not
afterward endure; and that Houston, learning the facts, left her
because he knew that her heart was not really his.

But the evidence is all against this. Had it been so she would
surely have secured a divorce and would then have married the man
whom she truly loved. As a matter of fact, although she did
divorce Houston, it was only after several years, and the man whom
she subsequently married was not acquainted with her at the time
of the separation.

Another theory suggests that Houston was harsh in his treatment of
his wife, and offended her by his untaught manners and extreme
self-conceit. But it is not likely that she objected to his
manners, since she had become familiar with them before she gave
him her hand; and as to his conceit, there is no evidence that it
