Every year or so, Lina and I make a children's book. Sophie in Paris is the fifth. And every time, once the books arrive, we hit the streets of Paris to deliver them ourselves. Bookshops, museums, all of it. This episode is about that part. Not the writing, not the illustrating, but the launching - which we find to be one of the most enjoyable bits. The envelopes, the deliveries, the doors we knock on.

So, for our second new episode this week, we're focusing on D for Deliveries.

Five books in, the operation has grown. This new book, Sophie in Paris, has been our biggest yet, and Lina and I sit down to talk through what that actually looks like from the inside.
