It's the end of the 19th century in England... Illuminating the nighttime streets of London covered in thick fog are gas lamps and the moonlight from between clouds. Ladies and gentleman, be careful on the streets at night. Things like scoundrels and mysteries hiding in the streets might be aiming at you. Cases too large for the highly prided English police force Scotland Yard are overflowing the streets. If you happen to get caught up in an incident...please prepare yourself to accompany it. A great detective with skillful intellect. A bold and fearless phantom thief. Now then, if Big Ben's ringing echoes across the streets of London, the curtain will open on love and adventure!
