When retired soldier Roland Kane arrives at the famous Elm Avenue Hotel in Azamford, he expects nothing more than a quiet holiday. But one mistake changes everything-he forgot to book his room. The only vacancy is Room No. 420, a room shrouded in fear, whispered about by locals, and permanently reserved by the mysterious Professor Bernard Blake. From the moment Roland steps inside, strange voices echo in the dark, his companion trembles in terror, and unseen forces warn them to leave before it's too late. Soon, Inspector Jordan and his children arrive, only to find themselves caught in a deadly game of shadows, vanishing guests, and bloodstained floors. Each locked door hides another mystery, each scream another clue, and every answer only deepens the horror. Why is Room 420 forbidden? Who-or what-lurks behind its walls? And why do the townspeople tremble at the mere mention of the professor's name? A chilling blend of mystery, supernatural suspense, and detective intrigue, Room No. 420 will keep you turning pages late into the night. Enter if you dare-but be warned: once you check in, you may never check out.
