Mr Oldcastle is judging a fancy-dress competition at a local school. The prize is a ride in his beautiful vintage car, but Gumdrop's been stolen! And Horace too! Who are the thieves and will Mr Oldcastle ever catch up with them? Gumdrop is the famous vintage car belonging to Val Biro. Together they travel the country visiting their many fans and appearing on television.
Val Biro (pronounced Beer-oh) was a children's author, artist and illustrator, was a native of Hungary, but was a resident in Sussex in England. He received his education in Budapest and London. His studio was located in Amersham in Buckinghamshire.
"I write so as to give my alter-ego a good chance for drawing pictures, though I find that the story I invent tends to run away with itself, leaving me, the illustrator, behind! Each story tends to be based on personal experience and, equally, each tends to grow out of that into the imagination. Each book seems to take a few months to gestate, and then I write it in one long day (or night)."
