After the First World War Bennett wrote two plays on metaphysical questions, "Sacred and Profane Love" (1919, adapted from his novel) and "Body and Soul" (1922), which made little impression. "The Saturday Review" praised the "shrewd wit" of the former, but thought it "false in its essentials ... superficial in its accidentals". Of the latter, the critic Horace Shipp wondered "how the author of "Clayhanger" and "The Old Wives' Tale" could write such third-rate stuff". Bennett had more success in a final collaboration with Edward Knoblock (as Knoblauch had become during the war) with "Mr Prohack" (1927), a comedy based on his 1922 novel; one critic wrote "I could have enjoyed the play had it run to double its length", but even so he judged the middle act weaker than the outer two. Sutton concludes that Bennett's "forte" was character, but that the competence of his technique was variable. The plays are seldom revived, although some have been adapted for television.
