There is also a clear attribution of Amsterdam to Holland in The Roundheads:

"Winter thumped the table. ‘I’ll say it is. He plies the route to Holland and back and that’s an end to it. I’ve never known him go across to France, not in all my years.’ Ben sat down. ‘Well, perhaps he’s trying out new territory. I mean, if everyone knows he does the Amsterdam route, they might steer clear of him.’"
