Protecting their own
At least 100 of them
Cycled off from St Peters Square
Like a goose leading their flock
Away from water
But instead dressed up
Like ghouls

Vampires

And zombies

Working in tandem
Shaping each wheel
With a burp
Instead of a beep
Across a river
Of closed shops
And boat like trams

Waiting in a different way
For the current to drop

And your text to 
Say you were on the way.
