Bertie and the Seven Bodies by Peter Lovesey
Monday’s corpse is fair of face,
Tuesday’s corpse is full of grace,
Wednesday’s corpse is full of woe,
Thursday’s corpse has far to go,
Friday’s corpse is loving and giving,
Saturday’s corpse works hard for a living,
The corpse that dies on the Sabbath day
Is bonnie and blithe and good and gay.
