This was, I told myself, a very bad situation. A very bad situation that could get a whole lot worse by calling the police and hanging around to answer their questions.

And yet, didn’t this go against everything I believed in, everything I’d ever told my children? How many clichés had I uttered over the years? Here’s a sampling: Don’t be afraid to get involved. Treat others as you would have them treat you. Don’t walk away from trouble. Own up to your mistakes.

And of course, my personal favorite: The policeman is your friend.

I was not sure, in this particular instance, that that was the case. I suspected that the policeman would not be my friend, and that by calling one, I might end up with a new roommate named Moose, who’d sleep on the lower bunk and want me to be his dance partner.

It’s probably worth pointing out at this juncture that I do not have what you’d call a long history with the law. I am not the kind of person, as you’ve probably gathered by now, who’s “known to police.” I’ve always played by the rules, paid my taxes on time, pled guilty to parking offenses and mailed in my check within a day of finding a ticket under my windshield.

So it’s safe to say that if the police were to find a woman dead in her garage, I would not be on the list of usual suspects. However, I could probably jump to the front of that list in no time by placing a call to the authorities to report the murder of a woman whose purse I had stolen only a couple of hours earlier.

As bad a day as I seemed to be having, I had to concede that it was a picnic next to the one Stefanie Knight had put in.

First, her purse is stolen, and when she finally finds a way home, some nutbar smashes her head in. What were the odds that two things that bad (the second one being considerably worse than the first) could happen to one person on the same day?

Unless, of course, the two events were related.

I was feeling pretty sick, and scared, already, but at that point a new chill swept through me.

Surely, there was no connection. It simply wasn’t possible that my taking this woman’s purse could have had, in any way whatsoever, anything to do with her death. The police might think so, but that would be an opinion formed through only a cursory inspection of the facts. I knew better. Just because two things appeared to be connected didn’t mean they were.

Then again, they might be.
