Mr Leatheran

In the novel One, Two, Buckle My Shoe, Mr Leatheran is a dentist who took over the practice of Henry Morley at 58 Queen Charlotte Street after the latter had been murdered.

Leatheran attested that, based on dental charts kept by Mr Morley, that the body of the dead woman thought to be Mabelle Sainsbury Seale was actually that of Mrs Albert Chapman.
