Manin's conjecture predicts the asymptotic behavior of the number of rational points of bounded height on Fano varieties over number fields. We prove this conjecture for a family of nonsplit singular quartic del Pezzo surfaces over the rationals. The proof uses a nonuniversal torsor. This is joint work in progress with Marta Pieropan.
