I had the same thing happen not long ago with a vintage knife I bought, I think it was UPS but may have been FedX. Tracking said it was delivered to my door but I was home and it wasn't. Called and they said it was delivered, I said no and it was an irreplaceable item. Well check your neighbor's doors, I already had. Mysteriously it appeared two days later on my door step. Maybe the driver remembered which door he delivered to and retrieved it.
