Coming up for me this morning.
Taking a quick look at the chart of someone known to be a con artist. I see (using Placidus):
1st House Neptune Sag. opposite 8th House Mars in Gemini - (a smooth talker) - negatively aspected: suspicious, projecting one's shadow, compulsive desires hidden behind a facade, tendency towards secrecy and manipulation
11th H. Pluto Libra opposite 5th House Jupiter in Aries (ripped off do-gooders, had a lawyer lover who protected them). Negatively aspected: Sex used to gain power, obsessive predator.
2nd House Mercury in Sag, opposite Saturn at 1 Leo (negatively aspected - a schemer, underhand behaviour)
A friend of mine's sister was just conned over the last year out of $40,000 in drips and drabs. It was unreal how easy it was to fool her. In the end she thought she'd only lost $10,000! Something tells me these con artists are really good at spotting a victim.
