🕵🏻♀️ I remember perfectly when Nancy Drew entered the reading radar of my younger self; it's in between the Enid Blyton and Agatha Christie phases. I also read Hardy Boys, but only a few, it's not as riveting as Nancy Drew (or Alfred Hitchcock's Three Investigators, which came to me at the same phase). The Hidden Staircase was the second in the series, and if I have read it before, I completely forget. So, I have read it as if it's my first Nancy Drew - and I loved it!
