England overcame a determined Bangladesh by four wickets to clinch a one-day series victory after another tense tussle in Chittagong.
Sam Billings, making his first ODI appearance in more than a year, and Ben Duckett both made half-centuries as England's makeshift top four put them in position to overhaul Bangladesh's 6-277.
Despite a brief wobble, Ben Stokes (47no) and Chris Woakes (27no) ensured the tourists claimed the spoils with 13 balls to spare at the Zahur Ahmed Chowdhury Stadium for a 2-1 series win.
After being put into bat, the hosts were indebted to Test captain Mushfiqur Rahim's unbeaten 67 off 62 balls as they flourished in the closing stages - in spite of Adil Rashid's ODI career-best 4-43.
England, though, were always ahead of the rate.
The decider had a fiery undertone after England captain Jos Buttler was reprimanded and opposite number Mashrafe Mortaza and Sabbir Rahman fined 20 per cent of their match fees following an angry exchange on Sunday, but there was no repeat incident.
Billings moved to a run-a-ball fifty shortly after England reached three figures, but was dismissed for 62 after top-edging a sweep to deep square leg.
Duckett brought up his second half-century in three matches off 56 balls but departed for 67 after scooping through to a diving Mushfiqur off Shafiul Islam (2-61).
Buttler and Ben Stokes kept the scoreboard ticking over, before Woakes closed the show with a towering six.
Earlier, Kayes was the aggressor in an opening stand of 80 before being dismissed for 46.
Mushfiqur was given a life on 44 after being dropped by Stokes, before some lusty blows gave England a testing chase, but one that was not enough as Bangladesh's pursuit of a seventh home series win in ODIs went up in smoke.
