A cool but pretty evening sounded ideal for a walk along the Liffey, so we walked up past the Brazen Head to the Liam Mellows bridge to the west, along Usher's Quay. We turned back east there, thinking to leap-frog back and forth across the river as we came to each bridge. The tide was low, but beginning to come back in.
We crossed the Father Matthew bridge back to the south bank, and paused along Merchant's Quay to take a picture of the Four Courts building across the river—that shot of the building with the rotunda—when we noticed a commotion a little further down the river, at the Grattan Bridge. A motor boat and two men in the river; four fire engines and an ambulance on bridge and bank; a good-sized crowd watching them search the river for something—or someone. We stopped and watched with everyone else, for 15 minutes or so, until the fire trucks began to leave.
It didn't look as though they found anything.
