James Ryan — a posh former soldier combining aspects of Johnson and Trump — is now PM, but remains suspected of being in Putin’s pay. It again falls to the MI6 officer Kate Henderson to handle this hottest of hot potatoes, since the Russian spy she tangled with before claims to have a kompromat video showing Ryan in Kosovo with under-age girls. There’s too little that’s fresh here, and much of it is implausible, but we get to accompany Kate on working minibreaks to any number of tourist meccas. Bradby’s portrayal of squabbling Whitehall folk continues to be intriguing and distinctive (and piquantly naughty, coming as it does from ITV’s chief anchorman). At the top level of politics and intelligence, he implies, if you’re not a sociopathic schemer, then you’re either burnt out, mentally ill or have a secret passion that will sooner or later ensure your downfall.
