Have the Big Bad acquire the services of one of the Realms' few immigrant Psions (a Nomad Psion in particular), and have them use their high-level psionic powers to redirect Khelben's and Laeral's next teleportation spells to a destination of the Big Bad's choosing. Nomad Psions can monitor teleportive activity with one of their powers (if they choose to learn the right powers), and then redirect it. In 3.0 the power is Divert Teleport, not sure if they changed the name or not in 3.5. In 3.0 at least, it's a 7th-level Psychoportive or Psychokinetic power. It allows a Will save and Power Resistance, so the Psion will need some significant stuff to boost his power save DCs. Power Focus, Greater Power Focus, high Dexterity (or Intelligence in 3.5), magic items boosting Dex (or Int), whatever else you can manage (like a Psionatrix of Psychoportation, a psionic item that adds +1 I think to psychoportive save DCs). If you use the Psionics Are Different rules, then Khelben and Laeral won't benefit from any Spell Resistance they may have through items or spells.
Redirect the teleportation to an area with an antimagic field (likely the Big Bad himself or herself with an Antimagic Field spell active on them), and proceed to melee them to death (an Assassin's Death Attack may be useful for that, or even a Rogue's Sneak Attack). Make sure the room they teleport into is small enough that the antimagic field fills it. If the room is filled with rogues, assassins, or other nasty melee damage-dealers, the two should perish quickly. If you want Laeral to survive and appear guilty, have her teleportation redirected instead to a room with an antimagic field and psionic Control Light making it dim, while the antimagic-field-generating NPC holds Laeral pinned (I'm sure a fairly strong Medium or Large NPC could hold the woman pinned down in a grapple, long enough for Khelben to be slain elsewhere). Then have the psion teleport Laeral to the tower, and Khelben himself as well, while leaving whatever's necessary to make it seem that she killed him (weapons or whatever). A bard can cast Memory Alteration or whatever to try and change her memories a bit, though it may or may not work (of course, you have creative license to say that it does, and just assume she rolled low on her Will save and the bard rolled high on his caster level check to beat whatever Spell Resistance she may have up after leaving the antimagic field).
Just create a disturbance somewhere in Waterdeep that would motivate the two to try teleporting there ASAP to deal with it, then divert their teleports, and have another agent get security forces up to the tower to arrive just moments after Laeral and Khelben are teleported back there, appearing that Laeral murdered him. While the two are away, some mage can use illusion spells to make it appear that Khelben and Laeral were arguing vehemently (any witnesses just have to hear it from outisde or down the hall, for instance, to think that it was real; no save unless they interact with the illusions). If the Memory Alteration works well, Laeral will really believe that she did murder Khelben in rage. In any case, it would be best if, while Laeral was away, someone got rid of her spells for the day, somehow, so she couldn't escape or whatnot after being teleported back to the tower. Unfortunately, it would be rather complicated coming up with something that might prevent Commune, Discern Lies, or similar spells from finding the truth.
