New companion, Mathew Sharpe (Mathew with one 't', Sharpe with an ‘e'!) is a space pilot from the future who has already been travelling with the Doctor for some time before we meet him in The Lure of the Nomad.

Listeners will recognise Mathew Sharpe actor, George Sear, from his roles as Arthur in AMC's Into the Badlands, Billy Cooper in Will for TNT, two series of Evermoor for the Disney Channel, and Friday Download for the BBC.

For thousands of years, it has drifted through space, unimpeded, forgotten, seemingly lifeless. Now, finally, it has been discovered.

Responding to a distress call from the mysterious hulk, the Doctor and his companion, space pilot Mathew Sharpe, walk into a desperate situation. The multi-tentacled semibionic Makara were tasked with renovating the abandoned craft, but now they’ve begun murdering their employers.

The Doctor soon realises that the Makara have been programmed to kill, but by whom, and for what reason? Finding out the truth will mean uncovering a secret that threatens the entire universe.

Matthew Elliott, writer of The Lure of the Nomad, told us about bringing this new companion to the Sixth Doctor: “It's been a great privilege to write the first of what I hope will be many stories featuring the Sixth Doctor's new companion, spacepilot Mathew Sharpe.

“As a courier of urgently-needed medical supplies, Mathew's ship is caught in an electromagnetic whirlwind above the planet Ormelia. It's only the timely arrival of the TARDIS that prevents poor Mathew going the way of his vessel. Despite the Doctor promising him just one trip through time and space, they've been together on a number of adventures when we first see them together in The Lure of the Nomad. Mathew is a good-natured soul, quite naive in the ways of the universe, and fiercely loyal to the Doctor; think of him as a cross between Steven Taylor and Harry Sullivan.

“I know it seems quite odd that I, another Matthew (with two 't's) should be writing the debut adventure of another Mathew, but I promise you, the choice of name was the decision of Big Finish script editor Alan Barnes. I'm not quite so egotistical as to demand that the new companion should share my name!

“Where he and the Doctor go from here, I really don't know, but I'm as interested to find out as everyone else!”

You are cordially invited to Argentia, the galaxy’s most exclusive tax haven, to attend the funeral of mining magnate Carlo Mazzini. The memorial service will be followed by music, light refreshments, and murder!

Carlo’s heirs have come to say their final goodbyes (and find out how much they’ve inherited) but when a masked killer begins picking them off one by one, Argentia goes into lock-down, closed off behind its own temporal displacement field.

Can the Doctor, Nyssa, Tegan and Adric apprehend the murderer before Argentia – and everyone on board – is forever cut off from the rest of the universe?
