"To all the young heroes who took boats, whether they vanished for ever in the Alboran Sea or reached the forbidden and longed-for shores, these pages are dedicated." Written from a single autochrome of the Archives de la Planète — the port of Algiers photographed by Frédéric Gadmer in 1929 — the volume belongs to the Fléchette series, which sets those plates in dialogue with contemporary writing.
