We examine our previous conjecture that the \ensuremathη^\ensuremath' intermediate resonance has the dominant role in the long distance contributions to B decay into two photons and a strange final-state hadron. We calculate the branching ratio of the exclusive \stackrel\ensuremath→BK\ensuremathη^\ensuremath'\ensuremath→K\ensuremathγ\ensuremathγ decay using the nonspectator mechanism for \ensuremathη^\ensuremath' production in charmless hadronic B decays. It is shown that the obtained branching ratio B^(\ensuremathη^\ensuremath')(\stackrel\ensuremath→BK\ensuremathγ\ensuremathγ)\ensuremath≈8.7\ifmmode×\else\texttimes\fi10^\ensuremath-7 is more than twice as large as the \ensuremathηc contribution to this decay mode.
