Witness to the late and sorrowful pact between predator and prey, spectator and species, Molly Bendall’s fifth book beckons the reader into the enigma of animal relation. “What’s left?” she asks. The answer is past remembering, attuned to extinction. Forsaking the names of creatures, Bendall returns like a sleepwalker to a painted habitat of swamps and savannahs, of captivity and display. At once playful and melancholy in its sifting of ritual discretion and shame, Watchful brings every sense, every measure, to bear on the blood mirror of the human.
