Chretien is nothing if not versatile: popular, recherche, allusive, insistent, arch, naive, racy and demure...He has a dramatist's flair for the handling of dialogue, a deft and economic way with characterization, the sharp confidence of the logician in his handling of rhetorical figures and the self-assurance of the entertainer in the deployment of humour (he is master of the verbal nudge). It is his essential vivacity that one misses most in his imitators.
