"So, did you trail my husband?" Gail asked the detective.
"Yes, ma'am. I did. I followed him to a bar, to an out of the way restaurant and then to an apartment."
A big smile crossed Gail's face, "Aha!! Then I've got him!" she said, gloating. "Is there any doubt about what he was doing?"
"No ma'am." replied the sleuth, "It's pretty clear that he was following you."
