That is a good, specific question, Puglover. Mercury is the tattler and in Scorpio, knows deep secrets (may know more than he or she even realises) and Scorpio is the zodiac Sign of death and investigations, so what Mercury knows can be serious, indeed. Mercury rules both II & Virgo. Virgo is the natural Sign of gardeners & landscapers & groundskeepers. If there is a Gemini who is a gardener, that person could qualify as the tattler too. It must be said, although I would rather not, that the tattler's slate is not clean either. So you have considered a possibility and it does fit. A snoop, a plumber, someone performing transport of the dead, a resource scientist, a junkyard or tip owner would all meet the case as well. Then again, we know that this Mercury tattling individual has reflex action with Neptune (the solstice point for Mercury) and Mercury is in Aquarius: groups, clubs, neighborhoods, emphasized by Neptune's placement in House 11. It is interesting and somewhat unusual that the solstice point of Mars is very, very tightly squared with Mercury. The Moon will be there on Friday, November 12 to activate the square. Meanwhile, Venus slides back into Mercury the night of Halloween.
