Dramocles: An Intergalactic Soap Opera (1983) - Plot & Excerpts
Treading the thin line between wheels-within-wheels mystery and shaggy dog story, this is dated but still justifies the jacket quote from Douglas Adams. I had forgotten almost the whole book since first reading it (the few exceptions inevitably including one of the mucky bits, plus the scene where two supporting characters try to engineer themselves a subplot to enhance their life expectancy), but there are definitely pastiches I wouldn't have registered as a kid, from Shakespeare to Robert E Howard - and I suspect a few I'm still missing now. And that lapse in memory seems fair enough given the whole plot, such as it is, rests on the listless monarch of the title learning that he has forgotten key details of his Destiny...which unfortunately oblige him to invade a friend's planet. Hijinks ensue.
