Has Bond sunk Solo?

I've recently finished William Boyd's attempt at a James Bond novel, Solo, and pretty thin fare it is.
It pains me to say this, as I've been a fan of Boyd's for a long time, probably since Brazzaville Beach. He picks diverse subjects to write about and his style is straightforward and without too many literary flourishes, though he's always been regarded as a posh novelist rather than a commercial one, I think.
