Heaven is in 'L'

Three months it was on a lonely road
In a strange city 'M' in a stranger country
Windy, cold and dark.

The contrast with a lovely time in 'D'
Just couldn't have been
Any more stark.

Rose a chance just then to visit 'L'
To be one once again for a while
To reignite the spark.

Pity, the visit over, to be back alone
Will see you again, this time in 'P'
My words you must mark.
