Play The Man Who Was Thursday — an interactive story where YOU are the hero

after the classic by G. K. Chesterton, 1908

Infiltrate a council of seven anarchists, each named for a day of the week, as the undercover poet-detective 'Thursday.' Unmask the others one impossible reveal at a time, flee across Europe, and chase the terrifying Sunday to the end of the world.

A moment from one playthrough

Across the breakfast table on the balcony, the enormous President Sunday leans in and murmurs that he knows you're a policeman — and that so, perhaps, is everyone else at this table. The other conspirators are watching your face for a flinch. Bluff it out and hold your cover, or gamble everything and accuse Sunday first?
