“All We Shall Know establish[es] Ryan beyond dispute as one of the finest writers working in Ireland today … It would be a bending of the classical definition to say that these figures are tragic – but in a way they are. As the book approaches its difficult conclusion, the possibility of healing, of atonement, is at least suggested by the narrator’s last, extraordinary gesture. Without disclosing the details of this final scene, it does not seem extravagant to claim it is worthy of Greek drama. That the tragedies of our own age happen in suburban semis, or on Travellers’ sites, does not make them any less cathartic – and Ryan’s choice of narrator, a character both deeply flawed and painfully guilty, shows him working in the great tradition of tragic fiction, his lonely adulteress coming to grief in the same shadowy spaces as Emma Bovary or Anna Karenina.”
