The Nancy Drew and the Hardy Boys Be a Detective Mystery Stories is series of crossover novels, it was published between 1984 and 1985, and was the first series to feature both Nancy Drew and the Hardy boys.

This series is the most different from any other Hardy Boys series because in these books the reader controls the outcome of the story by choosing different options of advancing the plot (similar to the Choose Your Own Adventure books).

1. The Secret of the Knight's Sword
2. Danger on Ice
3. The Feathered Serpent
4. Secret Cargo
5. The Alaskan Mystery
6. The Missing Money Mystery

Two more titles were planned but never published:

7. Jungle of Evil
8. Ticket to Intrigue
