Philip, Dinah, Jack and Lucy-Ann (not forgetting Kiki, the mischievous cockatoo!) are yet again caught up in another adventure. This time though, it involves a treasure map, a ship in a bottle and a dangerous gang of crooks! Jack's birthday present hides an awaiting adventure but the children don't know this yet. It is only until Kiki is blamed of breaking the ship in the bottle that the four children realise there is a map hidden in it, leading to an unknown treasure.Using the map's clues, they eventually find the treasure hidden in an old cave but unfortunately the baddies stumble upon it aswell. If you like adventurous stories then you will certainly like this one because I certainly did. It has lots of good moments where you don't know what's going to happen next.
