Simenon who has faltered of late is back in the form he's grandmastered -- namely a story of encroaching entrapment among ordinary people like the frugal young Frenchman Calmar who adventitiously acquires an enormous sum of money in an attache case (the contact who asks him to deliver it is found dead in the Simplon tunnel; the prospective recipient, a Lausanne manicurist, is already dead). But what can Calmar do with it under the solicitous eyes and nose of his wife and his colleagues at work, and how can he enjoy it or for that matter escape it? Unobtrusively, scrupulously convincing.
