Identification

Well I wiil try and explain what I mean a simpler way, we all have certain characteristics which identify us, for example my daughter identified me from a distance on a wet day with my hood covering my head by the way I walked, I don't have a limp which would make identification easier it's just simply the way I move, I am not sure whither I move like a panther or plod like an elephant and I didn't ask, so do we have identifieing characteristics in out writing even with a name change with which we can be identified from previous meetings, with some folk yes I can identify them while with others I can't. So as there have been several famous authors who have produced other novels under a different name some people have identified them by certain characteristics in their writing so I wondered if any members of the forum can identify some authors who have done this, I can't say that I ever have done this
