Vampire's "bed" (6)
I believe the answer is:
casket
'vampire's bed' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for casket that I've seen before include "Small box to hold jewels" , "Jewel-box" , "Box for jewellery or ashes" , "Helping boost" , "Small box for holding jewellery" .)
