Way out in the country, Mrs Topple is Tan's closest neighbour. But Mrs Topple has gone on a cruise and Tan is in charge of security at the Topple cottage. Tan is also looking after the garden and watering the plants. But mostly she's in charge of security. Which is just as well because something suspicious is going on. A strange car has been coming and going and a shadowy figure has been spotted snooping around. And now Tan has noticed items moving around in the garden - on their own! As tensions mount, Tan decides a stake-out is in order. Little does she know she is walking straight into a trap.
