“You should employ your little grey cells”
“... what would Poirot do? Poirot wouldn't flap around in a panic. He'd stay calm and use his little grey cells and recall some tiny, vital detail which would be the clue to everything.”
“I sprung you because I've got a message for you""doesn't your family own a cell phone company?""only a little one”
“Little deer, I've stuffed all the world's diseases inside you. / Your veins are thorns // and the good cells are lost in the deep dark woods / of your organs.”
“And therefore, Reader, I myself am the subject of my book: it is not reasonable that you should employ your leisure on a topic so frivolous and so vain.Therefore, Farewell:”
“To the delight of the poetic little gutter boys in the little grey streets.”
