city,” Dr. Blackwell remarked as they were eating their dessert. “I’ve arranged for Felipe to take you for a drive this afternoon. I’d thought I’d be able to accompany you, but a doctor’s time’s never his own, so I’ll have to depend on Florence and Felipe to show you the city.” “That’ll be fine!” exclaimed Peggy. “But we’re sorry you can’t go with us. Aren’t we, Jo?” Jo Ann nodded an emphatic assent and then went on to remark to Dr. Blackwell, “We saw something very interesting this morning—the old church back of your house.

I adore books—especially about old historic buildings.” As they rose from the table Peggy remarked, “Jo and I want to run across the Plaza to buy some postcards
