This is the main Finnish contribution to vagrant literature.
Tired of his life, a journalist picks up a hurt hare and does not come back to his wife, job, city, etc. He just walks through villages, works here and there, meets interesting characters. The way he leaves his life is interesting: he strips everything except his basic needs and those of the hare, and these eventually guide him. The animal is often the way in and out of the various worlds he crosses.

Beyond boomer humour (the snarky kind: the author is a bit too happy to display the shock of the common man faced with his character's abnormality), vagrant literature hits differently when the norms broken by the rebel are unknown to the reader, and 1970s Finland felt pretty foreign to me.
