On the same page the narrator takes a twenty minute stroll, which implies that the stroll is a "twenty stroll" and also a "minute stroll;" the narrator means that it was a "twenty-minute stroll." He repeats the same problem when mentioning the "ten minute bicycle ride" by omitting a hyphen between ten and minute.
Both of these items, though small, accosted me on the first page.
On the third page, I learned that the narrator "was stood before a beer tap at a bar." "Was stood?" Was standing, perhaps. Or had already drunk so much that someone had physically stood him up before the bar to prevent him from falling back down.
Either way, these features of Ewan's language distracted me. It's easy to overlook a mistake when reading proofs. but to have this many in the first chapter is an indication that more lurk nearby.
Next time.... I'll cover just a few of those.
