The Lovecraft Invasion (audio story)

 was the two hundred and sixty fifth audio story in Big Finish's monthly range. It was written by Robert Valentine and featured Colin Baker as the Sixth Doctor, Lisa Greenwood as Flip Jackson and Miranda Raison as Constance Clarke.

Publisher's summary
The Doctor, Constance and Flip join forces with 51st-century bounty hunter, Calypso Jonze, to hunt down the Somnifax: a weaponised mind-parasite capable of turning its host's nightmares into physical reality. Chasing it through the time vortex to Providence, Rhode Island in 1937, they arrive too late to stop it from latching onto a local author of weird fiction... Howard Phillips Lovecraft.

With time running out before Lovecraft's monstrous pantheon breaks free and destroys the world, the Doctor must enter Lovecraft's mind to fight the psychic invader from within.

Can he and Flip overcome the eldritch horrors of the Cthulhu Mythos? And will Constance and Calypso survive babysitting the infamously xenophobic Old Gentleman of Providence himself?

Continuity

 * The Doctor intends to keep the imprisoned Somnifax in his TARDIS's 'tertiary sock drawer'. He would later keep the imprisoned Carrionites in his TARDIS in his tenth incarnation (TV: The Unicorn and the Wasp, PROSE: The Taking of Chelsea 426, AUDIO: The Carrionite Curse)
 * Calypso Jonze told the Doctor that they couldn't think of a safer place to keep the imprisoned Somnifax than in the Doctor's TARDIS. Ironically, the Carrionites were still able to be a danger to the Doctor in his fourth (PROSE: Toil and Trouble) and sixth incarnations (AUDIO: The Carrionite Curse) despite being imprisoned.
