Titled Curtain Crawlers, the spooky tale is different to the previous run of Moon Queen stories, which feature Chris' very own take on superheroes and superheroines, for a number of reasons.
"Because of their content, the previous Moon Queen stories all use ROK Comics' 'R' rating," Chris explains. "Curtain Crawlers is the first Moon Queen story I felt could take the 'U' rating without bowdlerising it into nothingness."
The story also markes the first Moon Queen story where Chris has taken 'as read' the previous body of stories as knowledge that, really, is required of the reader - so if you want to catch up with what has gone before your best bet is to subscribe to the WAP subscription service for just £3 for 30 days, and then you can read all the earlier Moon Queen stories on your mobile.
"I wanted a to go back to a story like my prose novels that's a bit more than just one, however interesting, incident from Moon Queen's life," says Chris of the haunting 24-episode tale. "In Curtain Crawlers, I wanted to write more of a novel-length type of thing – to cover that sort of ground - even if the final story isn't actually very long.
My inspiration for this is the amount of content they fit into the 45-minute episodes of post-Eccleston Doctor Who," he reveals. "I sometimes think some of these these zip by too quickly for me to get a proper grip on them, but that's where comics have a unique advantage shared with text novels - that you can take them at your own pace and re-read at will!"
There are more developments in this story, further expanding the Moon Queen mythos. "By now, I wanted to link the stories a bit with the world and the journey of Mauretania Comics," says Chris, "from which so far Moon Queen's been at arm's length. So Garnet Ross from 'Pure Holiday' makes a cameo appearance (at quite an important moment) and the themes and the concerns of the whole story are quite Mauretania-like, connecting with 'Pure Holiday' again in using audio recordings as an element of the plot.
"I've even re-used one of the imaginary locations from 'How To Do Your Own Dentistry' for the place where 'our' Moon Queen is held while the story unfolds."
Chris was one of the first creators to give ROK Comics a try when it comes to bringing comics to mobile and has some useful tips on developing new comics for the young medium.
"I found 'mobile storytelling' simple to get into because I nearly always draw strips using a uniform panel size anyway," he says, "and my scenes are generally quite short, so the translation to 'page-by-page' format is straightforward.
"The most recent thing I've learned, in correspondence with [ROK Comics Managing Editor John Freeman], is that it's best to have very brief episodes starting with a one-panel recap using the final panel of the previous episode."
At present, Moon Queen stories can only be found on mobile and on Chris' official web site MetroPoppyfield. While there are no plans for a print edition just yet, Marc Baines at Kingly Books, who, among other titles, also pulished The Dial by Chris and Voice of the Wilberforce by Ed Pinsent, is planning a new edition of the Penguin Mauretania.
