A murder of silhouettes
I feel it is necessary to explain the title of this collection, taken from a song by Tom Waits: Alice.
As a group of chickens is called a peep, a group of ducks a paddling, a convocation of eagles, a murmuration of starlings, a wisdom of owls and a group of crows is called a murder of crows.
My title, therefore, refers to a group of dark shadows: a murder of silhouettes.
