Acknowledgments: Many thanks to those who responded to the "purse question" thread in the "Fanfic Related" MB's, where I asked what was the strangest thing that one had in one's purse.
Of the things that Lois had in her purse, half were from the respondents to that thread. I had the other half in my purse. (Yes, that is scary.)
Please ignore any obvious howlers in forensic science. I tried to gloss over my lack of knowledge as much as possible.
Also: what do you think!
