It always surprises me when I encounter someone so well read that they seem to have every obscure literary reference to hand and yet the late Canadian writer Mavis Gallant has managed entirely to escape not just their attention but their knowledge. ‘Who?’ they will ask. ‘How do you spell that?’ Offer them titles of collections and stories and their perplexity only deepens. The Uncollected Stories of Mavis Gallant, edited by American novelist Garth Risk Hallberg and published by New York Review Books, both tries to explain that underappreciation and to ensure that every serious reader knows precisely why one might wish to spend time in Gallant’s idiosyncratic and determinedly realist house of fiction.
