What's that? Timmy's in trouble... Timmy's fallen down the well. That's OK, because today's Little Golden Book is Lassie Shows the Way (The Authorized Edition), 1956.
Although Lassie may be able to warn the towns people about poor Timmy, he wasn't able to help me figure out who-dun-it, as just as the Sheriff shows up in the story, at the shabby farmyard where Timmy and his father, along with Lassie, who is about to point a paw the perpetrator, I find that the last page in my book is missing. Drat!
