I am putting together a scene which has a policeman and another male character in it. I am finding that constantly using "policeman" is quite repetitive, clumsy and interrupts the flow. I have tried to improve this by using the policeman's rank at times (eg. captain) but I am looking for some alternatives.
I previously used "officer" but my understanding is that this can also be a rank or type of policeman? If so I am concerned about calling one person by two different ranks. Similarly "detective" and "inspector" came to mind but again, based on my research I believe these are more specifiers of a type of policeman not necessarily something that can be used as a synonym for one.
The only other idea I have come up with is to simply give the character a name, although I was trying to avoid that as I'm trying to distance the reader from this character.
Any suggestions at all?
