Back in the field, roses were extraordinary cover. A messenger could hand off a stem in a crowded market without drawing eyes. The receiver, knowing which petal to check, could extract a microfilm, a pill, a mote of data tucked under the calyx. But the red rose did more than hide objects; it told stories. It was the symbol of a promise kept years ago, of a rendezvous under rain, of a life split into halves—before and after.
