For a very long time, Ashcan Pete was considered an amazing solo investigator because he had action compression. If you needed clues, he had a free move (or two) every turn. Now, he can double dip! He can even ready this with his power.
I can think of very few scenarios, even in four player, where you wouldn't at least consider this card. $2 and a play action for a free move action every turn of the game (with the conditional often being "you move before the rest of the party"). Surprised if this won't be errata'd to two XP.
A fun difference between this card and Pathfinder is that you can use it while enemies are on you. So if you leave a trap behind, loner and immediately move an enemy on to it (getting perhaps a free damage, investigate, attack or evade, or some combination of those with makeshift trap.) Even better, combine it with track shoes, and possibly get two free moves. It's expensive, but so is being trapped in the corner of a map because you can't get away from an enemy!
