The femur serves as a handle best, with it's thigh girth. After hushed
deliberation (the old man closes in!) a few rib bones are cracked (he
must hear!) and wrapped to the end of the femur with some strips of
the woman's flower-print dress.

locker.
You and Dave shudder as you delve into the poor dead woman's sack of a
body. Barbara, being religious, is praying over your morbid
enterprise.
