There has been plenty of speculation over the identity of the person hiding behind this explosive and unique voice since 2016, with Motorsoul, up to 2023, with the new La crònica diamant, being the sixth instalment of Motorsoul and Stalker's third work. Stalker has jealously guarded their anonymity so far, sending their texts by post to their publishing house without a discernible pattern and without hesitating to introduce contradictory information in the scarce news there is on their identity. Years after the publication of the celebrated Motorsoul, a book with four tales about invisible Africa, and En aquell cel brillen estels desconeguts, a novel that sets its action in Southern Sudan, and to mark the publication of their latest book, La crònica diamant, we ask ourselves: Are the rumours true that point to there being someone behind the mysterious pseudonym who knows so much about human health? We will discover that at the Festival 42, where Stalker will finally emerge from their anonymity, in a live, exclusive appearance in a conversation with their discoverer, the Chair of PEN Català and Raig Verd editor, Laura Huerga.
