Terror Tuesday: A Perfect Likeness

To sit to Hughain Mast was quite the coup,
So Lubay chose an outfit with more care
Than most would take o'er foodstuffs. "Show 'em through!"
Lu cried on learning Mast was waiting there.
Lu struck a pose and Mast began to paint.
The portraitist's stare was unnerving, yet
The prestige it conveyed! When Lu went faint
'Twas chalked up to excitement. "Did you get
My best side?" "Oh, indeed." That eerie grin!
Weeks passed. Each day Lu felt a bit less well,
While Mast's strange medium grew thick as sin.
Unveiling day, Lu stayed in bed a spell
While all admired Mast's lifelike masterpiece.
Lu's bones, meanwhile, had crumbled 'neath the fleece.
