An epic poem about the Trojan war is merged with the domestic heartbreak of the scholar who discovers it in this ambitious, structurally problematic novel

In Yann Martel’s fifth novel, a Canadian classicist, Harlow Donne, has been offered a year’s fellowship at Oxford University. His wife, Gail, has a full-time managerial job, and they have a seven-year-old daughter, Helen. Who will pour out her breakfast cereal and pick her up from school while Harlow is away? He and Gail quarrel. He leaves for England, and as she sees him off Gail whispers in his ear: “Don’t come back.”

So far, so everyday: but once Harlow gets to Oxford, the narrative shifts its form and becomes odder and more interesting. His prescribed task is to help sift through and translate a hoard of ancient papyri from Oxyrhynchus, in upper Egypt. It’s tedious work. Soon, though, Harlow is piecing together from words or half-words on wisps of desiccated reeds what he believes to be a long-lost epic poem. It relates the story of the Trojan war, but not, as Homer tells it, from the viewpoint of princely warriors and gods. The protagonist is a common soldier, a “son of nobody” named Psoas.

Biography mingles with fiction as Levy explores the avant-garde writer through the story of three female friends in Paris

The narrator of Deborah Levy’s witty scherzo of a “fiction” – “novel” isn’t the word for this uncategorisable book – thinks that Gertrude Stein would have liked Sigmund Freud. She imagines them enjoying a cigar together while their wives make small talk. Would Frau Freud “have exchanged her recipe for boiled beef with Alice B [Toklas]’s recipe for hashish fudge”? The two never met (though with her interest in the “bottom character” and his in the “unconscious”, Stein and Freud would have had plenty to talk about), but that barely matters. This book is full of things that don’t actually happen, of relationships that are not what the people involved suppose them to be, of digressions and fantasies and encounters that are imagined but never take place.

It all starts with a lost cat. The cat is called “it”: lower-case “i” followed by lower-case “t”. This causes all sorts of linguistic confusion, highlighting the way we use the word “it” to mean something indeterminate (as in the first sentence of this paragraph), or something trivial, or something tremendous. The phrase “lost it” recurs, the “it” meaning – variously – one’s mind, sympathy with Ernest Hemingway, daring to be as unconventional as Gertrude Stein, the stream of consciousness “flowing under the mowed and manicured golf courses on which men swung their clubs in the 21st century”, the temptation to smile while being undermined by a patronising man, the drudgery of housekeeping, the thing – which might be obedience or shame – that holds an artist back from becoming a modernist … or love, or one’s mother, or a black-and-white cat with one deformed ear.
