Kipling does mention a number of landmarks consistent with a 7-day run from Sunderland to Bilbao, such as "The Start" and "The Wolf." So most everything does make sense in terms of navigation. Somehow, the crew ends up in London, "Ratcliffe Road," for their spree; I can't find one in Sunderland but that's not a major problem.

Cheerily,
