Last Call at the Heron

The fisherman shouldn't have been on the dock after last call. But somebody met him there, and the last person to pour him a drink was Tessa Reyes. He'd been saying the salmon runs were being poisoned. His water samples are gone. The sheriff calls it a drowning. Tessa has his last tab, three patrons who remember the night differently, and a cab driver who swears he wasn't there. At the island salmon derby, she reads the tab aloud to the whole crowd. A we-solve-murders mystery for readers who know every confession comes with a receipt.
