A Fortified Vault Perimeter

Auditing wealth is worthless if the vault itself remains vulnerable to external displacement. Leaning my weight upon my cinnamon cane, I surveyed the low cavity beneath the sofa. While the matchbox and its peg deadbolt were sturdy, an unprotected flank invites ruin. Near the corner fringe of the woven rug, I located three heavy discarded upholstery tacks. Using the blunt rounded crook of my cane, I systematically rolled and nudged each brass tack across the dust-free floorboards, embedding them points-up into a tight triangular defensive perimeter directly surrounding the vault entrance. Not even a stray draught will approach my reserves unchecked now.
