Adam Weymouth’s Lone Wolf (Hutchinson Heinemann, £18.99), in which he walks “the faultlines of Europe” from Slovenia to Italy in the footsteps of a wolf named Slavc, is Book of the Week on Radio 4 from 11.45am today.

The journalist and writer Tobias Jones, who reviewed Lone Wolf in The Observer yesterday, said it was “an astonishing book, because the author, a rough-sleeping wolf tracker, has the humility to listen to all sides of the debate” over the return of the wolf.
