A very British murder scene

That tart
and arch
detective pose
of yours has walked
smack plumb into
a daydream dark
scenario. A corpse

with several suspects
due.

With whom you'll spar
and joust and test
your nose for
motive, character
displayed in arcs from best
to best, the better to
apply your arts

in cultured blur
of repartee
with facts arrayed
sharply-observed
and dressed
in trademark lavender. You'll need

- some else,
some touch,
some twist,
to set apart

yourself
from her,
or him,
or him.
The competition's
so passe, and well
outclassed. Well anyway.

No fictional parameter
could class with this. Accessorize!
Distinctive, slightly "off," not odd
but sharp. Impression
made to last, and just
your size.

A cane? No, lame. A...hat?
Perhaps, but
something, something more
trademarkable.

You stand in parlor,
with your corpse.

Deduction, or induction
waits
the suspects should be by
and by. You'll have
something to tell them all,
by then

no doubt remarkable.
But why?
