The last poem in the collection to address William Shakespeare's mistress directly, Sonnet 152 conclusively answers some questions, while leaving many old and several new ones open for us to ponder into posterity.

It asserts again that his Dark Lady is indeed 'dark', both in appearance and in character, and here makes a stronger than ever point of how he as the poet is perjuring himself by repeatedly, even continuously, saying things about her that are simply untrue; these things, notably, not being slanderous lies but favourable compliments.

The sonnet thus epitomises the form that Shakespeare with his highly unusual series either deliberately or accidentally creates: that of the anti-love poem to someone he just can't resist, even though he knows that in this he presents as deep a character flaw in himself as the ones he perceives in the person or people he professes to love or desire.

The heavily and obviously innuendo-laden Sonnet 151 returns to a struggle the poet purports to experience between what his soul – the 'nobler part' of his being – knows to be right and what his body wants and, with the by implication reluctant permission of the soul, then also gets: sex with his mistress.

Although coached in euphemism and metaphor, it is in fact one of the most sexually explicit sonnets in the collection and succeeds in leaving remarkably little to the imagination, once unpacked.

The at first glance unspectacular Sonnet 150 sets off from the base laid down by the previous three sonnets and now wonders out loud just how the mistress with her numerous and by now well established flaws and a beauty that could – according to these poems – be most charitably described as unconventional, manages to make our poet love her at all, and apparently prize her above all others, even those who, when looked at with a clearer vision and a less feverish mind than his, are objectively much more beautiful and agreeable than she is.

The conclusion it comes to though offers not only a fairly familiar observation that as the lover so enfeebled by your superhuman powers I surely deserve some love and pity from you, but also a surprisingly stark deconstruction, so as not to say demolition, of the lady's character in its entirety.
