Empty dolphin

The town has set up a couple of binoculars on the riverbank, so that we curious can follow the construction of the new residential area on the other side. My husband look at the building activities, but I do not, I see the dolphin that is now empty. Here the boat Gun and her unnamed friend-boat used to be anchored. But both have been salvaged after they sunk. Gun sank first  and the second boat sank just a couple of weeks after Gun. The police suspect foul play.
