Al piano di sopra il coro si scaldava la voce, nella sala degli archi si sentiva l’odore di colofonia e una nervosa allieva di pianoforte aspettava il suo turno. Vadim, il direttore, quel pomeriggio aveva detto agli insegnanti che l’anno dopo la scuola avrebbe potuto permettersene uno solo – e che aveva già fatto la sua scelta. Durante l’intervallo è stato trovato morto nella sala delle percussioni, accanto al timpano. Cinque persone erano vicine a lui, e ognuna ha rilasciato una breve dichiarazione – trova quella che era sola con lui.","rules":{"standard":["Ogni <b>riga</b> e ogni <b>colonna</b> contiene esattamente <b>una persona</b>.
