Home phone

The next day, Sofia went shopping for a new smartphone for Marcia. She explained.

"Tony's keeping track of where you and your phone goes. He's got one of those phone tracking app things. You're not to challenge him on it but use this phone whenever you want to go somewhere you don't want him to know about. Leave your other phone at home; you know how we women seem to lose track of things! If for some reason he tries to call you on your old phone, always call him back on it later to avoid suspicion."

"Neat!" exclaimed Marcia.
