I no longer have an interest in reviewing this title but would like to thank the publisher and author for the opportunity, it is now far past the publication and archive date. I have awarded 3 stars to keep this review neutral.

I was nervous, my affection for Katherine Woodfine (she is one of my favourite authors) hinges in part on the "gang" nature of Clockwork Sparrow etc. The loss of Joe and Billy over the course of these books is a big deal for me. This was a great extension on the Sinclair's novels, a surprisingly organic transition. I really appreciate how now Sophie and Lil are 17 and 19 we are getting new POV characters to keep this pitched at MG. Sad not to see a new "big bad" though - a great opportunity for something fresh.

I've read most of Katherine Woodfine's Sinclair Mystery series and knew i had to continue with the characters in the first book of this new series. I loved how Lil and Sophie are on two separate tasks that become one over the course of the book. Woodfine had me hooked from the second chapter and it was great to see the characters from her previous series with some new faces. I'm already planning on reading the next book when it comes out as i have to know what happens next!

As a big fan of the Sinclair Mysteries series, featuring Sophie, Lil and the rest of the gang, I was very excited to see that those 4 books wasn't the end of their story. Sophie and Lil now run Taylor and Rose Detective Agency and are so successful that they have others to work on the smaller jobs while they help out with the Secret Service Bureau! The book opens with Lil away on a secret mission and Sophie being sent to Paris to investigate the mysterious death of another British SSB agent. We learn about Arnovia, a tiny country nestled between Germany, Switzerland and Austria-Hungary and meet Anna and Alex, the young princess and prince of the nation.

All this comes together and we get to see some old characters and some new ones too. I love the girls in the book, they are so feisty, intelligent and independent. You can tell Sophie and Lil have grown up a bit from the last series, this one feels a bit more grown up and a teeny tiny bit darker (well, much darker as you can get for a middle grade novel!). It's probably because this is now their full time job, they're travelling internationally and the work is more espionage than detective work. Woodfine has done a fantastic job at research as well, nailing the Edwardian historical setting of the book. Only big downside is that Sophie and Lil don't see each other much and don't get a chance to eat cream buns while drinking tea! Hopefully this will be rectified in the next book in the series. A great carry on from the original series, Enid Blyton meets Sally Lockhart, with a dash of The Princess Diaries! Perfect for all ages

I've never read anything by Katherine Woodfine before but after reading this I'll definitely be picking up her other books! And the physical book is so pretty I might just need it for my shelf...

Peril in Paris is a wonderfully clever and perfectly charming historical mystery. It is a spin off of the amazing Sinclair's Mysteries series but works well as a standalone.

Sophie and Lil are such brilliant protagonists. They are clever, determined and adventurous, during a time period when that wasn't always appreciated in young women. The author does a great job showing some of the beliefs of the time, whilst letting Sophie and Lil prove them wrong with their actions!

The storyline is utterly engrossing. Chapters alternate between two mysteries, and I found myself hooked by both. It is well paced and full of enough twists and turns to keep me reading. The stories weave together by the end in a very satisfying way. I loved the Sinclair's Mysteries and think this has set the Secret Agents series up to be just as good, if not better. I hope to see many more!

Recommended to all MG/YA fans. This book combines the charms of a spy thriller with an action adventure, in a beautifully described historical setting.

Yet another stunning novel by Katherine Woodfine. This time her two heroines have moved on from working for Sinclair's Store and are running their own detective agency. They are sent on separate jobs but by chance they find themselves caught up in the preparations for a flying race from Paris to Berlin. The year is 1911 and there is espionage and treachery in the air, so both girls will need to be on their toes if they are to succeed with their missions. Another rip roaring read full of action and adventure.

A good old fashioned adventure yarn. I loved the historical setting and the subtle nods to classic adventure stories, not to mention the history of the British Secret Services (yes, I geeked out at the mention of 'C' writing documents in green ink). Fun and engaging characters too, and the two stories wove together nicely. Although this is the start in a new series, several of the principle characters come from Katherine Woodfine's other series about the Sinclair. Despite there being enough explanation to not feel completely lost, this did have the side-effect of feeling a bit thrown into the story with plenty of the girls' past adventures coming back to haunt them and accordingly having less emotional impact for me than if I had read the original series. That being said, you can definitely jump onto the series from here and I look forward to going back and reading about the Sinclair.

Reading this book on Kindle wasn't optimal either as there are a few letters which are enclosed as illustrations. I decided not to try and strain my eyes trying to read them as the print was small as well as being in a flamboyant font. It's not essential for the plot to have any of the information within the letters, but it still feels like an omission not to be able to read them.

Peril In Paris by @followtheyellow had me smiling until the very last page. The City of Lights is the perfect backdrop for more of Sophie and Lil’s adventures. I raced through the story as the plots interlinked seamlessly, enjoying every historical detail.
