The last week of April turned out to be the busiest of the month at Big Finish Towers, with three new releases and special reveals from across our entire catalogue. Let's dive straight in!

Monday morning saw Terrahawks: Volume 2 rocket into our ears, with eight new adventures for Dr. Tiger Ninestein (Jeremy Hitchen) and his team!

Based on the classic children's TV series by Gerry Anderson and Christopher Burr, this gripping new set pits the Terrahawks against both Queen Zelda (Denise Bryer) and some terrifying new enemies. Featuring some of the most spectacular battles to feature in a Big Finish production, you can order your copy today for just £25 on CD and £20 to download.

Next up, another group of heroes take on a new enemy in Pathfinder Legends – Mummy's Mask: The Slave Trenches of Hakotep. Starring Ramon Tikaram as Sky Pharaoh Hakotep, this new audio by Mark Wright sees the undead despot poised to invade the land of Osirion. With cities crumbling across the nation, it's up to Valeros (Stewart Alexander), Ezren (Trevor Littledale), Harsk (Ian Brooker) and Merisiel (Kerry Skinner) to defeat this ancient menace – if they can survive!

This double-disc story is based on Paizo Inc's beloved role-playing game, and can be yours today for £14.99 on CD or £12.99 to download. As with the majority of Big Finish releases, a complimentary digital download is included with CD orders. You can also subscribe to the whole run of six Mummy's Mask audios, or catch up with the first epic quest with our bundle of Rise of the Runelords.

Our final April release sees a Time Lord's ancient vendetta come to Earth in Jago & Litefoot: Series 11; featuring Christopher Benjamin and Trevor Baxter alongside Geoffrey Beevers as the Master!

Containing four new stories by Nigel Fairs, Matthew Sweet, Simon Barnard, Paul Morris and Justin Richards, this five-disc box-set also sees the return of Colin Baker as the Sixth Doctor, racing to aide the detectives against his old enemy. Get your copy today for only £30 on CD or £25 to download and explore the Infernal Investigator's previous cases on the range page here.
