Mrs. Pollifax‎ and The Second Thief by Dorothy Gilman Hardback

The assignment is a snap: Mrs. Pollifax just has to shoot some pictures at a quiet funeral outside Washington and take them to Sicily, where her old friend Farrell -- a former CIA agent turned art dealer -- anxiously awaits them. But like all Mrs. P's assignments, so ostensibly suitable for the CIA's favorite garden club member, this one quickly turns lethal. Her welcoming committee in Palermo includes a most unlikely CIA agent and several unseen enemies. Unfriendly eyes also observe Mrs. P's rendezvous with Farrell in a secluded mountain village and weapons are soon displayed. With mysterious forces hot after them, she and Farrell scurry for safety to a fortified country villa, where the bizarre chatelaine, once a star on Madison Avenue, is almost as unnerving as the dangers she's protecting them from.
