Recall that a group $G$ is a Camina group if every nonlinear irreduciblecharacter of $G$ vanishes on $G \setminus G'$. Dark and Scoppola classified theCamina groups that can occur. We present a different proof of thisclassification using Theorem 2, which strengthens a result of Isaacs on Caminapairs. Theorem 2 is of independent interest.
