Gary Oldman's Jackson Lamb is one of TV's best characters (Image: Getty) Slow Horses season 4 on Apple TV+ If Slow Horses was true, I'd be the first to come knocking on its grim-looking door at Slough House to offer them congratulations. But what would one say to spy boss Jackson Lamb, played by Gary Oldman, other than, “How on earth are you still alive?” followed by, "We'd like to donate your body to medical science..

.” I have already binge-watched the entire six episodes of series four. Of course I'm not proud of that.

It's what children do, but the show is completely addictive. After watching series four, I started to devour more of the first season -- much like Lamb would tackle a Chinese takeaway. And who doesn't like a character who puts their feet on a desk? “Yes, what is it?!” As you can tell, I’ve abandoned the normal way I would look at a show – that’s with only one eye open, and a sharpened pencil at the ready.

My only misgiving about the series is that it's not made by terrestrial television here. That said, Apple TV has done an outstanding job with the drama, giving it a lavish budget to spend on a peerless cast and eye-popping action sequences. Although I may not have called the shopping centre where the opening bomb attack happened, West Acres, which sounds like an unloved nursing home.

The show is a true ensemble. Although it has five-star actors, such as Oldman and Kristin Scott Thomas, often the plot is driven by one of the “horses”. Ever.
