Using a sample of 232x10{sup 6} {upsilon}(4S){yields}BB events collected with the BABAR detector at the PEP-II B factory we study the decay B{sup -}{yields}[K{sup +}{pi}{sup -}]{sub D}K*{sup -} where the K{sup +}{pi}{sup -} is either from a Cabibbo-favored D{sup 0} decay or doubly-suppressed D{sup 0} decay. We measure two observables that are sensitive to the Cabibbo-Kobayashi-Maskawa angle {gamma}; the ratio R of the charge-averaged branching fractions for the suppressed and favored decays; and the charge asymmetry A of the suppressed decays: R=0.046{+-}0.031(stat){+-}0.008(syst), A=-0.22{+-}0.61(stat){+-}0.17(syst)
