The Adventure Series

The Adventure Series features Jack, Philip, Dinah, and Lucy-Ann, a group of children who, together with their pet Kiki the parrot, get snarled up in the most amazing adventures you can imagine. They seem to be an adventure magnet, because they always seem to land right in the middle of it all despite their best efforts to have "a quiet holiday"... and if there's any treasure to be found then rest assured these kids will stumble upon it!

Each adventure takes place in a remote setting – an island off the coast; a castle on a hill in Scotland; a valley in a distant, deserted land; more islands of the coast; a mountain in Wales; a ship cruising around the Greek islands; a circus in the country of Tauri-Hessia; and finally a river in a faraway, ancient land.

1. The Island of Adventure (1944)
For Philip, Dinah, Lucy-Ann and Jack, the holiday in Cornwall is everything they'd hoped for—until they begin to realize that something very sinister is taking place on the mysterious Isle of Gloom. But they're not prepared for the dangerous adventure that awaits them in the abandoned copper mines and secret tunnels beneath the sea...
2. The Castle of Adventure (1946)
What is the secret of the old castle on the hill, and why are the locals so afraid of it? When flashing lights are seen in a distant tower, Philip, Dinah, Lucy-Ann and Jack decide to investigate—and discover a very sinister plot concealed within its hidden rooms and gloomy underground passages.
3. The Valley of Adventure (1947)
Nothing could be more exciting than a night flight on Bill's plane! But Philip, Dinah, Lucy-Ann and Jack soon find themselves flying straight into a truly amazing adventure. What has happened to Bill? Who are the two strange pilots, and what is the secret treasure hidden in the lonely valley where the children land?
4. The Sea of Adventure (1948)
When Bill takes Philip, Dinah, Lucy-Ann and Jack on a mysterious trip to the desolate northern isles, everything looks sets for an exciting time. But then Bill is kidnapped and the children, marooned far from the mainland, find themselves playing a dangerous game of hide-and-seek with an unknown enemy.
5. The Mountain of Adventure (1949)
Mrs Mannering thinks that a peaceful holiday in the Welsh mountains couldn't possibly land the children in another dangerous adventure. How wrong she is! Philip, Dinah, Lucy-Ann and Jack are soon up to their necks in the mystery of a rumbling mountain, roaming wolves, and a mad genious who plans to rule the world.
6. The Ship of Adventure (1950)
All aboard for a quiet cruise among the Greek islands! But when Philip's pet monkey breaks a birthday present, Philip, Dinah, Lucy-Ann and Jack are plunged into an exciting quest to find the lost treasure of the Andra—with some ruthless villains hot on their trail.
7. The Circus of Adventure (1952)
Why on earth did Bill have to bring the wimpish Gustavus with them on holiday? Neither Jack nor Kiki the parrot like the boy at all. But when Gustavus is kidnapped, along with Philip, Dinah, and Lucy-Ann, Jack must bravely follow them to a faraway country and unravel a plot to kill the king.
8. The River of Adventure (1955)
A river cruise through ancient desert lands will be an adventure in itself, think Philip, Dinah, Lucy-Ann and Jack. An adventure it certainly is, especially when Bill disappears and the children, along with Kiki the parrot, are trapped beneath a forgotten temple where no one has set foot for 7,000 years.
