"Lamb to the Slaughter" - I'm the Detective

If Iwas the detective investigating the murder of Patrick Maloney in "Lamb of the Slaughter" by Roald Dahl, I would have looked deeper in the story that Mrs. Maloney told me and take the process step by step. I would have hired FBI and probably call in the Husband's job and tak to his boss and co-workers. I would have cantacted his friends and see if they knew anything with him. I would have been a great detective.
