Credence

In 1920's New York a seventeen year old boy named John is planning to leave home. He wants nothing more than to be free, but his own personal vices, his abusive and vindictive "mother", and his poverty keep him locked in place.
Meanwhile Sherlock Holmes - a wealthy, twenty eight year old businessman - is living the high life; enjoying expensive luxuries, social status and sumptuous parties. From the outside it looks as though he's got it all, but in reality Sherlock has demons darker than the expensive suits he wears, and his life is much, much more empty than it appears.

Then by a surprise twist of fate, the two cross paths and what John initially thought to be the very best thing to happen to him; could quite possibly be the worst.
