Do you think my duaghter would tell my fiancee if i brought another woman in the house?

my fiancee is going out of town to her grandpas funeral and she will be out of town for a week and i think it will be a great time to score with another girl i have been intrested in but i was wondering if my duaghter would say something and if i had the girl over if my fiancee would find out since maybe the girl would leave a girl smell behind
