Welcome agents, we are WISE, World Immunity Systems, Europe and we work against immunological terrorism. This time, your task is to find a lost formula, connected to the further refinement of penicillin.
In 1933, the laboratory assistant Mary Hunt, who developed this unique formula, had to flee to protect it from falling into wrong hands, for example Hitler’s Abwehr. Getting stuck in Helsinki, Hunt decided to hide the formula in the city and burn all documents.
Last month, Hunt’s grandchild Laura found a letter from her grandmother, where she reveals her plan and gives some cryptic leads to the formula’s hiding place. It’s now your job to follow the leads and find the hidden formula. But please be careful – there are still organizations out there who’d like to have the formula for their own, sinister use.
