Anonymous Letter

I received an anonymous letter in the mail yesterday. It contained two things. This piece of paper in classic ransom note style, it reads: A competitor to you? Signed The Snitch. The second item in the letter was a business card with an url to a photo blog about Haninge. This blog about Haninge has been here for a decade so I don't think we need another one on the world wide web! The detective in me started working on the note and the card, but I couldn't identify the fingerprints, so I had to dig deeper. And it paid off. I will not name names but I do think I have a photo of the anonymous, (female) writer (C), and a person very close to her (M), whom I suspect is the anonymous blogger in question. Oh, and I have previously spotted C both at my local cafe and in the greenhouse in the park in Tungelsta. I don't miss much...
