I knew Nick Wallace before he was somebody. We both used to be part of the online Doctor Who writing group Who-ink – a forum for sharing and commenting on writers' attempts to pitch for the Virgin and BBC Books Doctor Who ranges back when that was something you were allowed to do. We also bounced around the same circles until we got chatting about Rebus and ended up forming our own mutual support network. We moved in similar circles, but Nick also had connections in places I didn't: he has worked frequently for Big Finish Productions, and that led them to offer him his first job editing a book – the collection of Bernice Summerfield short stories Collected Works.
When he got the nod, one of the people on his list of potentials was me: partly because we were friends, partly because our previous interactions "pointed to someone who knew how to write and write well", but also for two other reasons:
One, I was looking (in my own vainglorious fashion) to try to bring some readers of the DW book line over to BF's Benny line, so I was very keen to put together a Dirty Dozen/Expendables kind of authors line-up. A writing ensemble who would be enough to intrigue those who liked the Who books, but hadn't been tempted by the BF stuff.
Two, editing the book was big job that was going to take a lot of time and not pay that much, so I also wanted people I knew I could rely on to deliver a finished product which wouldn't need a lot of work from me.
