68: The Peregrine
Scrupulous attention to nature in all its wonder and horror, stunningly beautiful descriptions of the landscape and its inhabitants, a healthy dose of self-abnegating obsession, and dead birds that smell like pineapple.
The Sometime Seminar discusses The Peregrine (1967) by J.A. Baker.
