The House Without a Key [EPUB ebook] 

Enter Charlie Chan!
The House Without A Key is the first of the Charlie Chan mysteries. Atmospheric and entertaining, Biggers shows you a side of Hawaii that few will ever see.
John Quincy Winterslip travels from Boston to convince his aunt Minerva to end her extended vacation and come home. Nothing in his upper-class background could have prepared him for what he finds in Hawaii. Despite being engaged, Winterslip falls under the spell of the islands and meets an attractive young woman with whom he quickly falls in love. Almost immediately, he finds himself embroiled in a murder mystery. Nothing about his life will ever be the same.
