John has been at his clinic working when an email had come in from the blog he wrote. A young lady was needing help finding someone and she had no one else to turn to. John had answered the email and had the girl meet at the small pub down a block from the flat. Now he walked inside with her, looking at Sherlock and nodded. 

“Sherlock, this is Ms. Anna. She has a case for us...” Anna looked around the room and sat on the chair John pulled forward for her and then sat in his chair. Anna cleared her throat, clearly nervous. “I’m sorry to be a bother...even the police said they can’t help me...but I’m worried about an old friend of mine. You see, she was my college mate a few years back. We kept in touch since, mostly because we went thru a lot together back then. I’m a veterinarian you see, and she studied criminal law and such so she could became a detective. But when we left she was hired by a government group. She still emailed me until a week ago...I thought she was just out of town but then...I got this” 

She pulled a paper out of her bag and handed it to John who took it and read it thru. He frowned and handed it to Sherlock after reading aloud “Anna, I’m in trouble. You are the only one who knows the truth of back then...and now I have to hunt down the evil from that dark time...be safe and watch your back. Serena” John looked At Sherlock, eyebrow raised. 

Anna looked at the men and said “please...can you help me?”
