At a hotel in Buenos Aires, a woman checks in under a pseudonym. She wears a black fur shawl and has no luggage. She is alone.

Over the coming days and nights, she tells a story, which begins with a secret shared in a local bath house, revealing art forgery and fraud on a dazzling scale. At its heart is an enigmatic genius who for years forged portraits of the city's elite, before disappearing without trace. It is a story of influence and intrigue, in which nothing is as it seems. We're not to expect 'names, numbers or dates', she cautions, but a more subtle kind of reckoning...

Told in a mordant, irresistible voice and full of sharp surprises, Portrait of an Unknown Lady is a captivating enquiry into what we mean by 'authenticity', in life as in art. At once poised and capricious, elegant and bold, it is a thrilling exploration of the relationships between what is lived, what is told, what is remembered, and what is real.
