For Oswald Gubbins (Oz to his friends, Ozzy to no one), life as an estate agent is not going well. Nor is his love life, and his cat isn't too keen on him, either. Things can't get much worse... is what this idiot tells himself on the daily, but today, he couldn't be more wrong.

When Oz's boss, Horace Dreadnought, summons him to his office, Oz fears the worst. A sacking, perhaps, or another cyst appraisal. However, Oz is instead tasked with showing an old nightclub to Marsh, Waite, and Gilman, three mysterious new clients who just so happen to whiff of scampi. It's a sale which could turn Oz's life around once and for all, so long as he doesn't fluff it up.

It doesn't take Oz long to realise there's something very fishy going on and that what happens in Innsmouth unfortunately doesn't stay in Innsmouth. Oz is plunged into a terrifying world of Eldritch cults, secret organisations, never-ending roundabouts, exploding chip-shops, probable Kaiju, office romances, Elder Gods, inclement weather, and some very questionable acronyms.

The fish is about to hit the pan...
