The Detective Society has done it again. I asked you to send me pictures of you in your World Book Day outfits, and I was overwhelmed by all of the amazing costumes I saw! Thank you so much if you dressed up as my detectives – it’s hard to explain just how magical it is for an author to see readers bring their characters to life.

Below are some of the pictures you’ve shared with me. I think you all look absolutely incredible. I know I’ve missed a few here, and I do apologise – there was a particularly brilliant Alexander that I’ve mislaid somewhere – so please just let me know if you’d like to be included in this post.

I have the best fans in the world!
