(Now the contest is closing, I don't need to avoid giving away the answers.)
Harking back to a problem that many had with Q96 -
although the original British edition of Monopoly was based on London, when they decided to produce boards for other cities, there was one called the 'London Edition'. For some reason which I've not discovered, some of the properties were changed - in particular, the space originally assigned to Strand became Whitehall.
So it appears that Marion and Neville have this version - fortunately it doesn't appear that any other clues are affected (the Old Kent Road is still just after the start), but I wonder whether anyone submitting 'the Strand' should be given credit.
