Ryan Fraser scored a vital double as Bournemouth edged Everton 2-1 for their first win in nine Premier League games.
The Scotland forward plundered the Cherries' first league victory since November thanks to a late strike that flew home via a heavy deflection off visiting defender Michael Keane.
Idrissa Gueye's second-half goal had cancelled out Bournemouth's initial lead, but Fraser pounced to end Sam Allardyce's seven-match unbeaten start to life in the Toffees' hot-seat.
Fraser's double lifted Bournemouth out of the relegation zone and five places up the Premier League table, easing pressure on manager Eddie Howe.
The Cherries' first win since their 4-0 thumping of Huddersfield on November 18 ensured the Dean Court men avoided setting a hugely unwanted new club record winless Premier League run.
Fraser buried his opener with fine technique, hooking home on a late run into the box to punish James McCarthy for unwittingly playing in Callum Wilson.
The Everton midfielder's errant pass gifted Wilson a clear run on goal, the Cherries striker sent King down the right and the Norway forward's cut-back let Fraser finish with aplomb.
That proved the sole incisive raid of a lacklustre first half from both teams.
Wilson spurned a reasonable opening by blasting straight at Jordan Pickford, while an again subdued Jordon Ibe failed to conjure enough of a test for the Everton goalkeeper with a low strike on the turn.
The hosts lost influential forward King to a possible recurrent hamstring problem towards the tail-end of the first half, in another blow to Howe's apparently wafer-thin squad.
Bournemouth at least carried that 1-0 advantage into the break, whereupon McCarthy was ruthlessly hooked by Allardyce, with Wayne Rooney thrust into the fray.
Oumar Niasse was quickly pitched into battle too, and the double switch paid the craved dividend.
Steve Cook gifted Everton possession in the Bournemouth half, Gylfi Sigurdsson fed Niasse, and his smart flick positively begged Gueye to storm in and sweep home.
Bournemouth rallied well, but an unsighted Pickford produced a fine snap-save to deny Wilson, before Benik Afobe failed to connect with a header from point-blank range.
Morgan Schneiderlin deserved to see Everton leak a second goal for his woeful pass that set Afobe clear, but the former Arsenal youth star's heavy touch let Pickford clean up the danger.
Ibe struck the angle of post and bar from distance as the Cherries continued to press, but that ambition remained on a knife-edge and Nathan Ake had to summon a fine block to deny Sigurdsson on the break.
Just when Everton looked primed to hold on for a point, however, up popped Fraser again, running directly at the Toffees' defence and making no mistake.
The Scotland wing scythed in off the left, let fly - and bagged the Cherries their elusive win, via that hefty deflection off Keane, leaving a fuming Pickford to slam the ball into the ground when retrieving from the net.
