I think you're asking for the impossible.
Something attacks the party, they're going to be curious regardless of whether or not it leaves a corpse.
Unless you're having the party walk though the wilds and be attacked by wild animals there's going to be something deeper, or at least your players will think so.
I really think you would be better off if you could give us a more complete understanding of the situation. With the vague requirements you've given I simply think it's impossible. Especially if you have a curious party who is using speak with dead on everything to investigate why. Suddenly having something attack them which leaves no trace and gives them no leads is only going to make them want to investigate more.
Basically, an NPC will attack one of the party members alone while disguised into another creature (with a heightened illusory disguise), then after a few rounds it will feign death with the Drop Dead spell and leave. I cant't tell you the reasons for this (I know it probably makes no sense for you).I'm looking for a creature for him to disguise into. It can't leave a corpse because in that case, after a minute, the fake corpse will disappear and the player will, of course, suspect something weird happened. I also want the player to believe that the problem is solved once the creature is dead, avoiding any kind of investigation. The creature can't be incorporeal because he would notice that it is not, when he strikes it.
The npc will take the same disguise in the past days to scare the people in town, that will spread the word that "that creature" is causing trouble. So, knowing the player, he shouldn't suspect that something's fishy.
