Inspector Cadaver (Inspector Maigret)

Maigret's old colleague becomes an unexpected rival in book twenty-four of the new Penguin Maigret series. In everyone's eyes, even the old ladies hiding behind their quivering curtains, even the kids just now who had turned to stare after they had passed him, he was the intruder, the undesirable.
No, worse, he was fundamentally untrustworthy, some stranger who had just turned up from who knew where to do who knew what. Penguin is publishing the entire series of Maigret novels in new translation
