Using a sample of 232 x 10{sup 6} {Upsilon}(4S) {yields} B{bar B} 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 {bar D}{sup 0} decay or doubly-suppressed D{sup 0} decay. We measure two observables that are sensitive to the CKM 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.).
