Based on Wordsworth's 'Lucy'

He dwelt with me in Baker Street -

Our flat was just above -

A man who few did care to meet

And none prepared to love.

.

A genius, whose frailties

Were hidden from the eye;

Bright as a star, when only one

Is shining in the sky.

.

He lived unloved; but all did know

When Sherlock ceased to be.

Now he is in his grave, and Oh!

The difference to me!
