The speaker of "Miserly" is hiding. Someone creeping up the back stairs, afraid of being seen, already feels ashamed, and the odd image of "a crow for a hand" suggests why. The hand, which should reach out and touch or give, has turned into something dark, scavenging, and not quite human. A crow hoards shiny things, so the image fits the title: the speaker clutches what they have and can't let it go.
The second stanza shuts down even further. Being "heavy as a shut door" makes the speaker feel closed off, weighed down, and unwelcoming, perhaps even to themselves. The gold is all they have, yet it brings no comfort. It sits beside "a bed full of fear," where rest should be.
The mood is tense, lonely, and quietly guilty. Judging by the imagery, the poem shows how holding on to wealth can leave a person isolated, anxious, and cut off from other people.
