A modern-day Agatha Christie! Get ready to investigate the ODDLIEST of cases with the wonderful cosy mysteries of Agatha Oddly, the perfect series by Lena Jones for all readers ages 7+! 

Meet thirteen-year-old Agatha Oddly - a bold, determined heroine who has been a detective for as long as she can remember. All she needs is to break a first big case. And this stylish detective will stop at NOTHING.

In our first book of the series, the City of London is in peril of some strange goings-on and only Agatha can crack the case. With a scholarship to the prestigious St Regis School, a cottage in the middle of Hyde Park, a room full of beloved sleuthing novels, and a SECRET KEY that gives her access to a whole hidden side of London, Agatha will have to be careful who she trusts as she solves the gruelling mystery!

In book 2, there's been a murder at the British Museum and, although the police are investigating, Agatha suspects that they're missing a wider plot going on below London involving a disused Tube station, a huge fireworks display, and five thousand tonnes of gold bullion...

And in book 3, an assistant at the National Gallery has gone missing, but something bigger than anything she could ever have imagined takes her travelling throughout London. 

Agatha's stories are full of adventure, mystery and ... oddly things! 

If you love cosy mystery detective books and want more like this, you may want to take a look at some of our best crime and mystery fiction, the much-loved Murder Most Unladylike Mystery series or Montgomery Bonbon!
