Mercury in the 8th house

The 8th house covers shared money, intimacy, loss and psychological change. Mercury here investigates. These people ask the questions others leave alone, and they do well with research, tax, estates, editing and anything requiring a look underneath a stated reason. Conversation runs private and direct rather than social. The cost is a mind that keeps digging past the point of use, and suspicion that arrives well ahead of the evidence for it.
