She definitely used all that drama to sell books and benefited from it.
Which character in Troubled Blood is transgender? Is there a transgender character in The Ink Black Heart ?
It's not Dennis Creed as I recall from my reading some time past, certainly not Edie Ledwell.
The Spectator is a right-wing British newspaper with dozens of anti-trans articles and op-eds. The Scotsman and The Guardian also have very anti-trans skews. (The latter less so, but definitely more anti than pro overall.)
It's fair to say that fearmongering about trans people isn't the central focus of the novel, but she obviously knew exactly what she was doing and why.
And Barry Humphries is a beloved Australian entertainer who cross dresses. Neither are transgender.
Further, the prime suspect of the novel, Dennis Creed, is closely based on real life serial killers such as Angus Sinclair, Jerry Brudos, and Russell Williams who all share victim name details and traits with the fictional Creed, such as messing with bodies, fetishism, etc
None of these real life serial killers were trans gender, at least two cross dressed, and there are very few serial killers that lack a pathology.
There appears to be some in the world who will see a crime genre author write about a serial killer and immediately conclude that killer must be trans and some kind of transphobic stereotype.
I'm not one of those people.

The wikipedia page outlines the charge that it contains "pernicious anti-trans tropes" and continues:
