Jack Taylor: The Dramatist (Channel 5, 10pm) 

I'VE noticed that Iain Glen has a blossoming fan club across Europe partly thanks to playing Ser Jorah Mormont in Game Of Thrones, but also through his fleeting appearances as downtrodden and drink troubled private eye Jack Taylor.

The Edinburgh-born actor has managed eight episodes since 2010, based on the Ken Bruen crime novels, but is back with three two-hour shows for the cop who has a face more wrinkled than his disgraced old greatcoat from his days in the Garda Síochána (that's Irish national police to the rest of us).

On the subject of Game Of Thrones, Glen says: "It's been a real success even within HBO. I think they're confident that they're hopefully set for a few more years, which is lovely. A great thing to be a part of. The novels themselves are such vast canvases. You can worry that audiences won't manage to follow the various storylines, but I think episode by episode they do it very, very well."

Back to Jack Taylor, and for Glen, making this series was something of a dream come true.

"I've always fancied playing a private eye since seeing Chinatown, with Jack Nicholson," he explains.

Following an inaugural run screened last year on Channel 5, the crime buster is back for more, and in this episode our hero investigates the death of student Sarah Bradley.

She dies after falling from the roof of the university, dressed in a theatrical costume. A ring of paper wrapped around her hand contains a typed message.

The police assume she committed suicide under the influence of heroin, but Professor Gorman does not accept the Garda's theory and thinks his literature student has been murdered.

With help from sidekick, Cody, Jack tries to get to the bottom of the case.

Coast Australia (BBC2, 9.10pm)

After eight years of exploring Britain and Europe, Neil Oliver and the coast team have switched the land down under. This week I'm really jealous because I'm a fan of Bondi Rescue and will watch enthralled as the wonders of Sydney of revealed. While Oliver discovers how close the city came to being captured in the Second World War, Xanthe Mallett examines clever colonial DIY techniques for creating building-mortar from oyster shells.

The Quite Remarkable David Coleman (BBC1, 10.35pm)

THIS tribute, with a title taken from send-up show Spitting Image, aims to produce the finishing tape for sports commentator supreme David Coleman, who died last December.

On the day that Roger Bannister broke the four minute mile, Coleman made his TV debut and went on to host the BBC's Saturday flagship sport show Grandstand for a decade. In fact, Saturday just wasn't Saturday without Coleman's urgent intonations added to every sporting occasion.

He commentated on 11 Olympic Games, from Rome in 1960 to Sydney in 2000 and led to a series of Colemanballs books of sporting gaffes which entertained millions.
