"Another poem of waiting love is 'In Three Days.' And this has the
spirit of a true love lyric in it. It reads like a personal thing; it
breathes exaltation; it is quick, hurried, and thrilled. The delicate
fears of chance and changes in the three days, or in the years to come,
belong of right and nature to the waiting, and are subtly varied and
condensed. It is, however, the thoughtful love of a man who can be
metaphysical in love." (Stopford Brooke, _The Poetry of Robert
Browning_, p. 253.)
