Harvey Walters #16.
Extensive Research

The upgrade is a slightly stunty card that might find a home in any Big Hand Deck. This is more of the same, only slightly stuntier, and best suited for Harvey Walters, for whom it was literally tailor made. So much so that he probably doesn't want to spend the XP on the upgrade. Seekers are usually pretty good at finding clues in less complicated ways, but sometimes you just want to buy 2 clues and keep moving. Niche, but good in that niche.
