  We present a measurement of the Cabibbo-Kobayashi-Maskawa CP-violating phase
gamma with a Dalitz analysis of neutral D-meson decays to the K^0_s pi^- pi^+
final state from B^+/- -> D^{(*)}K^+/- decays, using a sample of 347 million
B\bar{B} events collected by the BaBar detector. We measure gamma = (92 +/- 41
+/- 11 +/- 12)deg, where the first error is statistical, the second is the
experimental systematic uncertainty and the third reflects the Dalitz model
uncertainty. For the ratios r_B^{(*)} between the magnitudes of amplitudes A(B-
-> D^{(*)0}K-) and A(B- ->\bar{D}^{(*)0} K-) we obtain the one-standard
deviation intervals [0,0.14] and [0.02,0.20], respectively. All results
presented here are preliminary.
