In this essay, a parallel reading of "Les Liaisons Dangereuses" by Choderlos de Laclos and "William Lovell" by Tieck is carried out. Structural correspondences (both are epistolary novels) are intertwined with the elements of a thematic continuity, linked to the logic of the intrigue. Nevertheless, while in Laclos the seductive strategy that pervades the plot develops according to a linear pattern and finds its accomplishment in the realisation of the erotic desire, in Tieck the fulfilment of the sexual tension is overturned in a nihilistic disenchantment devoid of any possible remedial.
