PLOT
Neves and his wife Celia are the owners and managers of the 'Little Star Pension', a familiar hotel that caters to bourgeois family and would-be actors, instead of the ill-reputed 'Good-Night Pension' (just across the narrow street), where gigolos, whores, and criminals of all sorts may go for a quick encounter. However, not all is well among the ten residents of 'Little Star Pension': each dialogue line from every hotel guest is evidence that he, or her, has a reason (actually, more than one) to hate Neves - to the point of wishing him dead. Carelessness (or devious intention) by one party will provide the means; another, will create the propitious moment; yet another, and then the rest of them will create the festive New Year's Eve occasion - to do with Neves forever! Obviously, only the famous world private-eye Hércules Pirôt can solve the crime... for which he is called by phone, even before the deed is done.
