His options few, his future bleak,
John Watson frets, but isn't weak.
Goes out, he knows not what to seek
And finds a man who's dark and sleek
Who always looks to see.
And in Bart's lab he seeks a boon;
Asks him 'round to visit soon
(Seven hours after noon)
Two twenty one, flat B.
Murder's made and sleuth's invited.
John abandoned feels he's slighted,
Then remembered grows delighted;
Suddenly, new purpose sighted
Sherlock makes him happy.
Poison pills, four victims sicken
Killer's foiled in game of chicken
Danger done, they homewards quicken
To two two one, flat B.
