Elementary, bro.

I recently finished posting a multipart Elementary/Sherlock crossover story ("The Tale Of The Two Sherlocks") and decided to expand it into a series called "The Family Business." Currently I have a 10K big bang fic that will be somewhere around the fifth or sixth story in the series finished, and then I will be writing a 15K big bang story set immediately after that one as well. My current beta is a Sherlock fan but not an Elementary fan, so I need a beta who is familiar with both shows to look it over. Mostly I'm looking for a character/content beta, but I wouldn't mind if they're a SPAG beta as well. I know I had issues with my BBC!Sherlock sounding like Elementary!Sherlock, and I want to make sure I don't go that route again.

The only thing I suggest is you read the first story in the series to get an understanding of the AU I've created (that story is 14K long). Pairings in the series include Elementary!Sherlock/BBC!Irene, BBC!Sherlock/Molly, John/Donovan and past Elementary!Sherlock/Donovan. Most characters who are major characters on both shows have been included in at least the first or fifth/sixth story. Any help would be appreciated. Thanks!
