Absolutely essential reading for fans of Roger Delgado's Master and Ian and Barbara. In each case, McIntee manages to expand the character considerably while remaining true to the performance set by the original actor. The Master in particular is a real joy - the next best thing to a lost TV story - and in a speech on honesty, in which he defends his 'principles', McIntee nails the ambiguous appeal of the character as Delgado played him: that for all his evil there was a perverse sense of decency about the man.
Another ambiguity, the relationship between Ian and Barbara, is sensitively explored, as are the effects of their adventures with the First Doctor (you didn't think they could walk away from them unscathed, did you?). As if this wasn't enough, there's a surprise guest appearance, a surprise (well, to be frank, almost implausible) tie-in with a TV adventure, some touching revelations about the Master's past and a wonderfully lurid evocation of the London underworld circa 1976 (knew those old Sweeney videos would come in handy).
There's also no Doctor, but you'll be having too good a time to notice that.
