Like Lockwork
You slide your shank in slow and smooth,
To dock upon the centre-post;
And now a gentle twist affords
To ease your teeth between my wards.
Your bit precise in ev’ry groove,
Your diamond-pick a torsion ghost:
A skeleton to probe my fob,
And whispers through – an inside job.
You push your shaft deep in the plug,
And stroke my barrel from within.
My tumbler spins, my cams engage,
My deadbolts throw and springs assuage.
My keyway holds your bittings snug
To activate each driver-pin
To line the shear as each is shipped –
Then enter in – my locks are tripped.
