RossChris: Thanks for the additional comments, FIrstGofer and Coochies. I am at a loss to explain how "fencing" has worked as an answer; but heigh-ho, the grid says it was right so well done you! (3 months, 1 week ago)
FirstGofer: Enjoyed it... would have struggled to see the groups without Pevensie and Let Tam but after that fell into place. Couldn't get the Watson connection though. Well set, as usual :-) (3 months, 1 week ago)
Coochies: That Konta crossover is delicious.
One thing on the Kirrin-Pevensie-Brown-Banks group, typed in "fencing" as a complete guess and somehow got awarded a correct answer. I'm not complaining, will take the points wherever I can find them! (3 months, 1 week ago)
RossChris: Thanks for the comments, Mister Tom and koshatnik. Of course you are right about Nerf being a brand created by Parker but it made for a better anagram than anything I could get from Fisher-Price and other manufacturers! (3 months, 1 week ago)
koshatnik: Four satisfying groups, thanks RossChris. The family set was one I should have identified, but didn't (3 months, 1 week ago)
Mister Tom: Very nice... spotted the 4 groups but let down by a childhood bereft of Blyton.
Fern is strictly a brand, but it's clear enough what you meant. (3 months, 1 week ago)
