Find your mirror

One is a sub-chief of London's most dangerous criminal gang of the late 1930s, who has made a name for himself by dint of being respected.
The other is a weird inventor, with a big heart and a mind that travels even faster than his camper.
What do they have in common? They are each other's mirror, they just don't know it yet ...
Everyone can fall in love, but only a lucky few in the world can find true love, the person they are destined to, their soulmate.
Bartemius and Jonathan just have to find out.
