I tore the top edge of the yellow paper envelope.

The ripping sound was loud over the falling rain.

I tipped the ragged opening toward my palm.

A silver metal key slid out and dropped into my hand.

It wasn’t a normal house key or car key.

The metal was thick and rectangular, with a small round hole drilled through the top corner.

It looked like something from an industrial padlock or a secure bank lockbox.

I rubbed my thumb over the flat surface.
