Because Potter is Allergic to Poppies

If you like mysteries, crime novels or get weak knees when you think about Draco Malfoy in a healer/mediwizard outfit then be sure this book is what you're looking for!

One day Draco surprisingly gets assigned as Auror Harry's mediwizard and personal spy in the hospital, as someone is after Harry's life. Draco searches for evidence and clues who the potential killer might be. Along the way he discovers information that brings them closer to catching the criminal.
While working together both Harry and Draco not only uncover the person who threatens Harry's life, but also their feelings for one another...

Concerning the mystery and crime part of this fanfiction I would give it at least four stars, but I could't warm myself to Draco's and Harry's interaction and their developing romance. It was lacking the necessary something that would keep me cheering them on to get to the kissing part, although I found Draco's characterisation quite well done.
