What happens to checks after they’re cashed?

I wasn’t always a hitman.

One morning a sinister-looking pen appeared on my cubicle desk.  Somebody called for my boss; I wrote down their name; the line went dead.  Turns out they disappeared.  Turns out anybody’d disappear after I wrote their name with that pen.

Red ink.  Blood-like.

I made millions.  The ultimate hitman.  No mess.  Even I didn’t know where they went.

Until I got careless.

Helplessly I stare up from the paper; two-dimensional; nothing but a name written in red ink.  And I wonder, what happens to checks after they’re cashed?
