Brendan Gleeson continues to impress in Mr Mercedes, it's the last round-up for Frock Finders and Vogue, while The Middle returns for a final season

Pick of the day

Mr Mercedes, 10.15pm, RTÉ One

If there's any justice in the world, Brendan Gleeson should waltz to an Emmy next year for his remarkable turn here as foul-mouthed retired cop detective Bill Hodges, haunted by a serial killer.

In this week's episode, the cat and mouse game between Hodges and Brady escalates, Hodges has an upsetting conversation with Janey’s mother, while Deborah’s drinking almost causes an accident at the Hartsfield home.

If you haven't seen this show yet, do yourself a favour and get over to the RTÉ Player and get cracking with the back episodes.

As we get reacquaint with the Hecks, eldest son Axl (Charlie McDermott) returns home from his summer trip to Europe, sporting a man-bun and embracing a new, chill European outlook on life.

Chris Packham: Asperger's and Me, 9.00pm, BBC Two

For most of his life, broadcaster and naturalist Chris Packham didn’t tell anyone about the one thing that in many ways has defined his entire existence.

He has Asperger’s Syndrome, which means he struggles in social situations, has difficulty with human relationships, and is, by his own admission, 'a little bit weird'.

But what if there was a way of taking away these autistic traits? Would Chris ever choose to be 'normal'?

Here he invites viewers inside his autistic world to try to show what it’s really like being him.
