Follow the adventures of Theo Duncan  the son of the Prime Minister  and Samira Jhor, his school friend.

Join Theo and Sammy as they try to solve mysteries that have baffled Parliament.

This series is perfect for readers aged 10 years plus, who have enjoyed other middle grade mysteries, like Murder Most Unladylike and Adventures on Trains, and are ready for their next adventure.

Mystery in the Palace of Westminster is a great adventure which romps along with humour.

Georgina, Reviewer

The book explained the inner workings of parliament in an easily understandable and age appropriate manner, making it a great introduction to politics for children.

I would have absolutely loved this book as a kid, and still thoroughly enjoyed it as an adult.

This book would be a great introduction to politics while also offering a twisting mystery to entertain readers.

I adored this book, it was just the sort of book that I liked to read as a child.
