Sherlock Holmes fans' will find this simple.

Mr. Lal was having an early walk. He had just crossed a bridge when he saw a crowd of people. Rushing to them, he found that they were crowding around a dead woman. Lal was a famous detective. He took the case and started his investigation. The woman seemed to have come for an early walk, too. Seeing her handbag lying nearby, Lal ruffled through it and found what he wanted - her identity card. Her name was Lakshmi, and her house was about a ten minute drive away. Her number was also written on her card. Lal phoned the given number.

"Is this Lakshmi's residence?"
"Yes. And I am her husband. What do you want?"
"Sir, your wife is dead."
"What! No way!"
"Sir, come here quickly."

About ten minutes later, a car pulled up. The husband got down, and on seeing the woman, rushed to her and started crying. Lal was about to console him when something flashed in his mind. He quickly had the husband arrested. Can you tell WHY..??????
