The Black Box (La boite noire)

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!
