For a free–field flat monodromy defect, a formula for the finite part of the correlator is obtained as a double power series in (1 − x ) and (1 − x ) where x and x are lightcone coordinates. It takes the particular form of a series in (1 − x ) with coefficients finite sums of hypergeometric functions of 1 − x and is identified with a bulk block expansion. An expression for the coefficient of the (1 − x ) n (1 − x ) m term is thereby found as an explicit function of the flux and dimension. Some typical examples are presented. A transformation allows the bulk block expansion to be written as an Appell F 3 function which has simplifying consequences.
