We search for the decays B- -> phi K- gamma and B0bar -> phi K0bar
gamma in a data sample of 228 million BBbar pairs collected at the
Upsilon(4S) resonance with the BaBar detector.  We measure the
branching fraction B(B- -> phi K- gamma) = (3.5 +/- 0.6 +/- 0.4) x
10^-6 and set an upper limit B(B0bar -> phi K0bar gamma) < 2.7 x 10^-6
at the 90% confidence level. We also measure the direct CP asymmetry
in B- -> phi K- gamma, A_CP = (-26 +/- 14 +/- 5)%. The uncertainties
are statistical and systematic, respectively.
