I remember reading this English short story during my school days; it was part of our English curriculum 18-19 years ago.
It starts with a wife killing her husband with turkey or chicken or some other food item : not a planned murder but one in anger during a fight. Then the murder investigation starts and a police constable tries to figure out who killed him, but he fails and didn't even get his hands on the murder weapon. In the end, the wife offers him a dish made out of the murder weapon and he starts eating it while either he or the wife says something like:
Sometimes evidence is just under your nose and you fail to find it.
While evidence was literally under his nose.
