Pay attention to any nagging thoughts you have when Mercury sextiles Pluto on October 30th. It may be a question that isn't easily answered, a stubborn doubt that won't go away, or an inconsistency in someone's story that just doesn't sit right. You'll want to wave it all away – especially now that Mercury's in Sagittarius – but don't. The only way to resolve this kind of uncertainty is by doing some painstaking research. It may be tedious and slow but what you wind up with will be worth the extra work. Not only does it avert a disaster, but you'll be presented with an unexpected reward.
