Vintage set of 6 books from the Three Investigators series. All in relatively nice shape, aside from the usual wearing of cover edges, corners, etc.. Phantom Lake is in especially nice condition. Three of them have some stage of spine detachment problem found in many of the trade edition hardcovers. Those three are Whispering Mummy (pictured and fully split), Flaming Footprints (just starting), and Dead Man's Riddle (also just starting to crack). All have the blue graveyard endpages. A wonderful addition to someone's collection!
