Usually, January is a time for enforced sobriety and regretting the post-Xmas overdraft.

Not for the Slow Horses.

Season four was a family affair specifically, Rivers family.

Lets dig in to the finales twists and revelations.

Final spoiler warning…

Why Did They Let Frank Harkness Go?

Not in any official capacity, of course, but in an under-the-table arrangement.

Jack Lowden as River Cartwright in Slow Horses season 4

So they let him go.

What Happened to the Psycho Gulf Prince?

(We still dont know who the target of that assassination was.)

No matter, because Franks blackmail terms included MI5 getting the psycho gulf prince off his back.

They presumably did, and he was free to walk.

Why Was Frank Trying to Kill Chapman and Cartwright?

He paid it off.

In the first decisive act ofWhelans dithery cant you do it, mum?

Story-wise, his decision also ramped up the finale peril nicely.

Is Catherine Standish Back Now?

She certainly seems to be.

Whos Karla?

A little nod to a character from the world of spy authorJohn Le Carre.

When Is Slow Horses Returning?

We dont have a date, but season five has already been filmed and so is currently being prepared.

Expect it to arrive in 2025.

Most Important of All…How Did Standish Know Where Jackson Lamb Kept His Handcuffs?

Were sure shes just very organised.

Nothing to see here.

Slow Horses season 4 is available to stream onApple TV+.
