Detective Comics, Vol. 1

Castle With Wall-to-Wall Danger - Batman and Robin chase a lead on a bank robber to England, where they find their suspect merely bears a striking resemblance to their quarry. They stay for a meal, but soon find themselves the victim of several suspicious accidents.

Puzzle of the Purple Pony - While en route to a rodeo, Ralph and Sue Dibny spot a man painting a pony purple. Overcome with curiosity, Sue forced Ralph to stay behind and solve the mystery. It's a good thing she did, as some gun-toting varmits are also apt to get involved.
