No matter what else I’m reading, I always have at least one mystery novel on my nightstand. At the end of a long day of bad news — far too frequent, these days — I need to dip into an orderly world where justice prevails. Yes, I know some mysteries deviate from that pattern. I don’t read those. How do I know whether a mystery fits my criteria? I read the last page first. Real life is surprising enough! Plus, I nearly always forget the identity of the murderer by the time I get to the end of the second chapter.

When I’m out and about, I enjoy mysteries also. Sometimes they show up in an overheard comment: “He’ll do for a starter husband” (one twenty-something woman to another) and “Have you brought your business to a successful conclusion?” (dog walker to poodle). Before you ask, yes, these are real things New Yorkers said.

My favorite mysteries appear on signs. Here’s one:

No one can read this without wondering which ingredients the store won’t sell. Unethically sourced shea butter? Uranium? Magic beans? It’s a mystery.

Here’s another mysterious sign:

Let’s get practical: How does the site owner know what parents have said to their kids? Does telling children of the dangers of trespassing fulfill the parents’ obligation? (“I told you, now go and trespass if you want.”) Also, isn’t trespassing anywhere a dangerous activity? Or only on this site?

Another mystery:

I’m ignoring the subject-verb agreement error (Shower Caps should Keep, not Keeps). What I really want to know is whether there are Shower Caps that make hair wet. Also, is there a shower cap that keeps something other than HAIR DRY? Maybe there are Shower Caps for toes? Or belly buttons? Elbows, perhaps?

The mysteries presented here don’t conclude with justice triumphant, but neither do they honor the guilty. They’re just mysteries that add a little fun to my life and, I hope, to yours also.
