A Murder of Crows

One of my Christmas presents that turned out to be extremely interesting reading. A journey through the strange stories and mysterious cases that have contributed to British murder law. 
And now I know that the collective name for crows comes from the fact that flocks of the coal black bird  would scavenge of the bodies of the dead , drawing it to battlefields and graveyards and perhaps alerting people to the presence of a murdered body. The British vulture.
