Laurie and Gertie will lose everything unless they fix their time machine. Will their puzzling new Italian friend help to solve a Pompeian murder mystery?
The Emerald Serpents is the first in a series of time-travel adventures that features 12-year-old tomboy Gertie and her timid twin-brother Laurie.
After their grandfather dies Laurie and Gertie discover a time machine in his secret workshop, but what good is a time machine that doesn’t work when you’re about to lose your home?
Their only hope of keeping the bailiffs at bay is a nationwide school history project that promises a £5,000 reward. Laurie is determined to win, but the school bully has other ideas. A terrible storm provides unexpected assistance in completing the time machine, but can this – and Francesca, a fellow pupil and feisty Italian girl with a mysterious background – help the twins save their home?
Follow the twins and their cheeky terrier Britney to Pompeii, 79 AD, where they meet bloodthirsty gladiators and murderous villains, and with the deadly volcano about to erupt - and Gertie accused of murder - will the twins ever make it back to the present alive?
