At first glance, Alice Luxley invites natural comparisons to Dr. Milan Christopher, but with more careful consideration, it becomes clear that she's a completely different beast altogether.
Ms. Luxley's reaction ability seems quite unremarkable in solo mode, but becomes noticeably stronger on teams - the larger, the beter. The reason is that if you're playing solo and you're at the same location as an enemy, you are most likely engaged with it. Thus you're probably spending your actions fighting (or otherwise dealing with the enemy) rather than looking for clues. As such, Alice's reaction ability is going to trigger a lot less frequently than you'd probably like for that 4-resource installation cost. Now, there are other ways to discover clues that won't trigger an attack of opportunity (Working a Hunch, for example), and sure, it's great to be able to dispatch a Whippoorwill or some other Aloof enemy; but these situations tend to be exceptions, not the rule.
On the other hand, with more players you'll frequently find yourself in situations where an enemy in engaged with another investigator, and this is where Alice's ability really comes in handy.
As other reviewers have mentioned, she's a good fit for Carolyn Fern, but I think she's even better with Roland Banks. With Roland, you can set off a nice chain reaction where you kill an enemy, thereby discovering a clue, and finally using Alice's ability to damage (and hopefully kill) another enemy. Timed correctly, Alice and Roland can do some real crowd control. The nice part about this combo is that since no investigation actions are required, Alice is maybe OK even for solo Roland (but I still think he has better ally options).
I don't know if I'd seriously consider Alice Luxley in a William Yorick deck (with his lower ), but you can see the potential for some fun combos there as well.
