Sherlock in Love -- by Sena Jeter Naslund
Sherlock in love is an entertaining enough novel, but despite some indications of possible slashiness, well--not to give too much away--that doesn't happen. As a novel in its own right it is mildly amusing but not particularly strong as pastiche or as a literary novel.
