Four reasons why "Game of Shadows" is slash fanfic:
- All close female characters are quickly thrown away, killed or left at home. Yes, there is the gypsy girl, but when is she ever represented as a love interest?
 - One character is repeatedly hurt, with close reaction shots from the other. Including the full range of h/c standards from loneliness and grief to torture and near death (repeatedly).
 - Anachronism, implausible physics and misappropriation of canon is rampant. Canon elements (yes, I mean you Reichenbach falls) are blown hugely out of proportion.
 - One character proves himself unable to stay sane alone, the other needs to be rescued from a villain.
