As I said.
Had it all worked out; all my co-conspirators lined up. The get-away driver, hideouts and alibies.
I was in the bank, holding up the teller. Saw, in my mind, all the lovely cash already in my bags.
And then, sirens! Police cars pulling up outside. Officers storming in.
Turns out, somehow, someone had intercepted some part of my planning and let the authorities know.
Well — no harm done, no cash had been delivered across the counter.
So glad I dodged that one!
