I'm sure I shall - it's years though since I read them, so it will almost be new territory.
I might look into getting the subsequent books from the library. Our local library closed down recently, but a new one has just opened down on the village High Street. I will take a wander down and see what they have to offer.
(I'm reading a Michael Connelly at the moment, so they will have to wait until I've finished that).
Aren't you going to read "Swallows and Amazons" yourself?
