Tonight's TV: Joanna Lumley's Silk Road Adventure (ITV, 9pm)

Joanna Lumley's Silk Road Adventure (ITV, 9pm)

THE eponymous host is off on her travels again, following in the footsteps of David Baddiel, whose recent exploration of the Silk Road was also compelling TV.

Her first stage is in Venice, where Joanna discovers how the Silk Road helped the region's merchants and the city state itself grow rich and powerful. She witnesses evidence of Marco Polo's silk road booty, and sees how silk cemented Venice's reputation as a centre of luxury and wealth. Later she's off to the Balkan country of Albania, and Turkey, starting in Istanbul.

It's a pivotal Silk Road city on the crossroads of Europe and Asia. There's time for a look round Cappadocia, where the amazing rock formations create a unique landscape that became both a sanctuary for travellers and the early Christian communities. After a 14-hour journey to the far east of Turkey, she enjoys a spot of cheese-making, before heading into the highlands close to the Georgian and Armenian borders.

Ill Gotten Gains (BBC1, 7.30pm)

YOU could be forgiven for thinking that Deep Rummage was an indie folk band, rather than a team of law enforcers.

Here cameras follow the story of the largest drug bust in British waters as the Tug Boat MV Hamal is stopped by Border Force and searched by said team. Over in Merseyside, a drug-dealing gang is raided and authorities seize everything they can find at the team's houses. Plus, a look at how criminals' assets are sold at a Proceeds of Crime auction, and we follow the sale of an enormous Hummer vehicle used to smuggle a huge cocaine haul.

The Supervet (C4, 8pm)

IN the first of a new series, Professor Noel Fitzpatrick and his team treat a giant Newfoundland puppy with a painful knee and shoulder. What appears straightforward quickly turns into a much bigger concern, and Noel and his team are challenged to invent not one but two new implants for her. Meanwhile, a rescue black Labrador called Moogi is in need of treatment for severe elbow arthritis, and a golden Labrador born with a deformed front paw is offered a bionic solution in the form of a unique, custom-made prosthesis.

Upstart Crow (BBC2, 8.30pm)

WILL looks forward to an age when anti-immigrant rioting is long-gone, but in the meantime he and the players plan to do their bit to help those worse off than themselves with a fund-raising charity gala night.

As it happens Will's newest play, the Merchant of Venice, is also about an oppressed outsider - but who will play the ground-breaking character of Shylock? Step forward the great actor of the age, Wolf Hall, a man with amazing stage presence and some rather controversial theories about who really wrote Shakespeare's play.

Trust (BBC2, 9pm)

GIVEN the soap opera-style life of the Getty family, one of the 20th century's most iconic dynasties, there was little wonder TV and film makers would be keen to dramatise it.

Now the dream team of Slumdog Millionaire/127 Hours writer Simon Beaufoy and director Danny Boyle join forces again for this saga reminiscent of recent Ridley Scott/Christopher Plummer movie All the Money in the World. It boasts a starry cast, including Donald Sutherland, Anna Chancellor and Brendan Fraser. In the first instalment, J Paul Getty Sr, one of the world's wealthiest men, looks to the rest of his family for an heir to his oil business after the suicide of his eldest son. Harris Dickinson also stars.

DIY SOS: Grenfell (BBC1, 9pm)

PART two of two. Nick Knowles and the team build a two-storey centre for the community to use as they decide.

Rosalyn and her family have lived on the Grenfell Tower estate since it was built in the 1970s. She runs a dominoes club for West Indian pensioners and hopes the new centre's meeting place and cafe could provide a new home for the group. Nick also meets up with Nabil, who lost six members of his family in the fire, and discovers that there is a need for the delivery of mental health services. Finally, the Duke of Cambridge drops by to meet local residents and talk to firefighters who were among the first responders on the night of the tragedy.
