Graham Oakley's "Church Mice" picture books are a delight. They're about the adventures of a cat, Sampson, and his two mice friends who live in a church with other mice residents. I've only read two of them, but I re-read them frequently during my youth. They were The Church Mice Adrift and The Church Mice Abroad. Aside from the charming stories, the illustrations are packed with detail and tons of puns and jokes that one always seems to miss during the first read. Much like science books filled with cut-away illustrations, Graham's books always kept me coming back for another pass.

I'm currently reserving as many unread ones as I can from my local library.

In the process of researching Oakley, I discovered he drew books other than the Church Mice series, including some about a team of anthropomorphic English police foxes(!). One of the "Foxbury Force" books is available at my local library; I'll check it out and let you know how it goes.
