It's quite an elaborate scheme   The fine art of poisoning   The dose to comatose   Slyly administered      Not for the frail of heart   The vengeful must play their part   A friend to the bitter end   Or so they say      Nice and slow   Misfortune will flow      Peril in the nursery   It seems a tainted pastry   One bite what a dreadful fright   She was such a delicate little dish      A pleasant parlour gathering   Quicksilver concealed in a ruby ring   Two lumps or three   I have always adored bergamot tea      Nice and slow   Misfortune will flow   But who will know?
