No doubt, the borrower was coy.
All those years on Shetland Isles watching
Two generations of idle tales between two sheets
After forty years on the shelf it was time to come clean
Dust off the covers, brazen the danger of having to pay dues :
Bloodshed : A dagger drawn menaces the reader
Eyes stare back lured to the front pages
For the promise of a classic whodunnit
The hint of murder spiced up a life
Threats of library fines were dismissed
In the end, a spot of Spring cleaning
Revealed the tome which was returned
Fines capped at three pounds and sixty
A steal.
