🔍 The book was published in 1965 as part of the beloved Three Investigators series, making it the fourth entry in the original run. 👻 The story's central location, the Mathias Green Mansion, was inspired by the real-life Winchester Mystery House in San Jose, California, famous for its bizarre architecture and haunted reputation. ✍️ Robert Arthur Jr., who created the series, was also a respected writer for radio programs including "The Mysterious Traveler" and "The Shadow." 🏰 The book features one of the series' most memorable elements: a secret headquarters hidden in a mobile home junkyard, accessed through a series of tunnels. 🎬 Alfred Hitchcock appears as a character in the book (and series), though his involvement was purely a licensing arrangement, and ghost writers wrote his dialogue and introductions.
