In the title compound, C(23)H(17)NO(3)S, the mean plane of the benzo[b]carbazole ring system makes a dihedral angle of 77.17 (4)° with the phenyl ring. The S atom is in a distorted tetra-hedral configuration. There are three intra-molecular C-H⋯O inter-actions forming five- and six-membered rings with graph-set motifs S(5) and S(6), respectively.
