A luxurious crystal is hidden deep underground, which the inhabitants of Foggy Albion call the Heart of London. The townspeople carefully guard the priceless crystal and other artifacts belonging to the heritage of the Secret City. After all, if all this falls into the hands of malefactors, then troubles cannot be avoided: the city is threatened with exposure, and its inhabitants - gnomes, lacrians and jotuns - a miserable existence and subordination to dangerous criminals.
Recently, London has been covered by a wave of crimes related to an attempt to take possession of a magic crystal. Mortimer's criminal syndicate is involved in this, which intends to win the right to be the owner of priceless treasures at any cost. The police are trying to catch the criminals, but these efforts do not give any result. And the detective, who was entrusted with the investigation of this case, completely disappeared without a trace.
Go to the city shrouded in mist and secrets, get a map of the area and start your own investigation. To find out who robbed the Artifact Bank and who is hiding under the invisibility cloak, you have to get useful equipment, complete dozens of difficult and unusual tasks and solve a lot of tricky puzzles.
Useful inventory will be waiting for you at colorful locations. It's just that it won't be that easy to find it. Tools, rags and other necessary gizmos hidden from the eyes will have to be searched in a pile of rubbish. If you get bored looking for them, you can replace it with a Match 3 game at any time and get a valuable inventory item in a more fun way.
All your tasks, as well as found notes, secret ciphers and newspaper clippings with possible clues will be stored in a special diary. By connecting all these threads and passing dozens of tests - restoring images, opening tricky locks and hacking a computer - you can get on the trail of criminals and prevent the death of the Secret City.
