Liz Harper's to-do list as boss of Happy Maids:

• Drive to new client's palatial Miami beach house, armed with housekeeping kit
• Try to stay upright when discovering he is none other than Cain Nestor, a reclusive millionaire and infuriatingly distant ex-husband.
• Keep tight-lipped about the secret that made you walk out on your marriage
• Let him see the new you - a successful business owner. Don't let on that he's making your heart beat twice as fast as normal!

Above all, remember to be professional—you're not here for romance!
