Mercury in the eighth house
Mercury in the eighth house thinks about what is concealed. Research, investigation, psychology, debt and inheritance draw the mind, and the person is good at the paperwork nobody else will read: wills, taxes, joint accounts, the fine print of shared money. Conversation reaches serious matters quickly and small talk is a chore. Secrets are kept well. The demand of this placement is to speak what has been worked out, since a mind that only gathers and never discloses turns its findings into weight.

Which sign holds it
Under whole-sign houses the rising sign settles every other house at once. If you know your Ascendant, this is the sign your eighth house holds and the planet that rules it.
| Aries rising | Scorpio · ruled by Mars |
|---|---|
| Taurus rising | Sagittarius · ruled by Jupiter |
| Gemini rising | Capricorn · ruled by Saturn |
| Cancer rising | Aquarius · ruled by Saturn |
| Leo rising | Pisces · ruled by Jupiter |
| Virgo rising | Aries · ruled by Mars |
| Libra rising | Taurus · ruled by Venus |
| Scorpio rising | Gemini · ruled by Mercury |
| Sagittarius rising | Cancer · ruled by Moon |
| Capricorn rising | Leo · ruled by Sun |
| Aquarius rising | Virgo · ruled by Mercury |
| Pisces rising | Libra · ruled by Venus |
Quadrant systems such as Placidus cut the houses by the angles instead, so a planet near a cusp can land in a different house from the whole-sign answer. The chart page shows both.
Reading it in context
A keynote is a starting point, not a verdict. What Mercury actually does in your eighth house depends on its sign, its aspects, its dignity, and whether it is in sect. Two people with the same placement and different charts around it live it differently.
