British Readers: Who Are These Stories REALLY About?

A few days ago I wrote that Edward Marston's "The St. Valentine's Day Massacre" and Anthony Mann's "Esther Gordon Framlingham," both in The Best British Mysteries 2005, put me off somewhat with their self-referentiality (though the Mann, especially, has some very funny dialogue). Do any British readers know those stories? If so, are the stories taking potshots at anyone in particular in Britain's crime-fiction world?
