Break-Up! — Gerry Conway

The world-famous Hardy Boys have been solving mysteries together for years, but the unthinkable has happened ― Joe and Frank have decided to no longer work together. Like Lennon and McCartney, Martin and Lewis, and Sonny and Cher, all things must pass. Will they continue as agetns of A.T.A.C.(American Tenns Against Crime) separately? And will Joe and Frank still be effective as solo crime fighters?
