On Saturday 26th March I launched my fourth book, Jolly Foul Play, in London’s Covent Garden Waterstones. I have to thank the resourcefulness of the Waterstones Trafalgar Square staff, who were so enthusiastic about the event that they did not let a flood in their basement stop it, and the generosity of the staff at Waterstones Covent Garden, who stepped in to host at two days’ notice.

The store was set out beautifully, with huge piles of all of my books. Seeing the four of them together as a series is still incredible to me – I can’t believe that I wrote all of them!

We had a bunbreak set out, of course, with ginger beer and lemon shortbread biscuits that I baked myself.

I was overwhelmed by the wonderful fans who came along – some of you dressed for the occasion, and some even brought me presents! I enjoyed meeting each and every one of you, and I thought your questions and ideas were fantastic. I even met some girls whose whole class were writing a Murder Most Unladylike TV show!

Thank you so much for being there, if you were – and if you couldn’t be, I hope I’ll see you soon! Below are some pictures from the events. I had such a great time, and I can’t wait to do it all again in Birmingham this Friday!
