Two Dogs

ONE SULTRY MOONLESS night, a leopard escaped from a circus and slunk away into the shadows of a city. The chief of police dogs assigned to the case a German shepherd named Plunger and a plainclothes bloodhound named Plod. Plod was a slow, methodical sleuth, but his uniformed partner was restless and impatient. Plod set the pace until Plunger snapped, “We couldn’t catch a turtle this way,” and bounded along the trail like a whippet. He got lost. When Plod found him, half an hour later, the bloodhound said, “It is better to get somewhere slowly than nowhere fast.”
