The Black Box [Version française]

Images flash through Arthur's brain, voices buzz in his mind, uttering disjointed words and sentences. Arthur Seligman seems to have had an accident but did he run over a little boy or not? And what was he doing near Cherbourg while he lives in Paris? When he regains consciousness (but does he really?) Isabelle Kruger, a nurse, tells him that he had lapsed into a coma after his accident and that she wrote down all of what he said while he was delirious. She gives him the notebook and Arthur starts investigating...HIMSELF!
