"Together for the first time," the cover proclaimed. Nancy Drew and the Hardy Boys: Super Sleuths! was published in 1981 by Wanderer Books, and was later reprinted in the same format by Minstrel Books (both imprints of Simon & Schuster).

Frank and Joe meet Nancy in seven short stories:
- Mistaken Identity
- The Pirate Cove Treasure
- The Armored Lady

- Clue in the Chimes
- The Secret of Mountaintop Inn
