Sock Poppet at Play

I just finished this book. It was okay, nothing special. Except for one little error than is unlike any I've ever seen before. Check out a couple of the many examples.

"There was a long silence, and Andrew finally said, 'Not in the least, Farrell. I know you will do whatever must be done to achieve your jail. If keeping Lilly safe is your jail, then I know you will die trying. But I do not think this is the sort of marriage...that is...'"

   "Devlin laughed. 'Do you think for a single moment that he would even acknowledge me? Or that I want that?'

   'Perhaps not. But for Miss O'Rourke's sake, I would think you'd be willing to make that compromise.'

   He thought about that for a moment, but he could not escape his inevitable jail. 'If we should find that Olney and Rutherford are involved with the Brotherhood, the cachet of the Rutherford name will not lift me any higher than I am at the moment. The scandal will finish the family.'"

I have a hunch that the mystery word is supposed to be goal. With the British spelling of jail being gaol, it's an easy switch of the a and o to make the word goal. Would it be possible to accidentally substitute the word "jail" for the word "goal" that way?

I checked out reviews for the book on Amazon and GRs but could find no mention of this strange phenomena, though it certainly took me aback quite a few paces.

I even looked up the definition of "jail" just to make sure I hadn't lived my whole life unaware of some obscure meaning for the word.

Is there anyone who can figure this out or do I need to file this under "Things That Will Keep Me Awake Night for Years to Come?"
