The great detective was staring at the door, as he had done for the past two weeks. He needed a case to occupy that mind. Thankfully today the door opened and Holmes had a case.

A man stepped in and introduced himself as Mr. Mokko.

“Watson, here is a man having troubles with Perl.”

“Holmes, how can you know that?”

“We can tell from the lines on his face, the stiff wrists and the pads of his fingers that he a much maligned sysadmin; from the Hawaiian shirt and the hat that he’s into the Perl scene. The scowl and the fact that he’s here on our doorstep tells me that he’s having troubles.”

Holmes looked back to the man and said, “Come now, you must tell me the tale.”
