Behind the Case

Watercolor designs for cozy mystery readers, made by a human (and one suspicious cat). Each design starts with a small image in my head — a teacup, a stack of vintage books, a question: "what if my cat actually solved the murder?"

I publish a new case file every day or two. Drop a line at adam.pawel.rakowski@gmail.com if you've got an idea.
