Six weeks and we’d be through with seventh grade! Three other girls and I had spent the last half hour hiding near the old white farmhouse. Screened by of budding gooseberry bushes, our eyes were zeroed in on its diamond-shaped attic window. I handed my homemade, cardboard periscope to Shirleen. I’d built it that morning from instructions found in Volume Eleven of my mother’s 1943 Richards Topical Encyclopedia. The instrument consisted of two oatmeal boxes, small mirrors from the lids of empty Avon compacts, scraps of cardboard and miles of masking tape.
