Nate The Great And The Sticky CaseBook - 1978
A stegosaurus stamp belonging to Nate's friend Claude disappears, and the indomitable Nate the Great is called in on the case. At first, even Nate is stumped -- the stamp has just vanished without a trace! But with clues from the weather and his ever-faithful dog, Sludge, Nate is soon on his way to wrapping up his stickiest case yet.
