Issue 15 of Vortex - the Big Finish magazine is now available online for free and includes me rabbiting on about how Graceless came about. There'll be plenty more on Graceless as we approach the release. Sorry.
Also, director Neil Gardner has a few things to say about the audiobook of The Slitheen Excursion. I listened to it for the first time yesterday and am very pleased. Though Neil seems to have missed that the book is a serious and gritty exercise in documentary realism, on the model of the Killing Fields.
