Through a lot of that, Miles has a sidekick, Ian Vorpatril, who's the Watson to his Holmes in many ways. Not dumb, but often looking so next to his genius cousin, Ian is always getting in trouble with or over women.
Which is pretty much the entire premise of Ian's first solo book. It all really does involve a girl. And Imperial headquarters. And moles in several senses of the word. It's not a particularly deep or thoughtful book - in fact, I'd call it a caper novel - but it's a lot of fun...even if I found parts of the plot horrendously predictable.
I still recommend it if you like your science fiction more to the sci-fi end of things and a good story.
