Solution

The 10 lead runs round to Southís J.  South leads the ♣K, which is won by Eastís ♣A.  Eastís best (or, at any rate, most dramatic) return is the Q.  Spurning this Greek gift and the opportunity to pick up the trumps for no loser, declarer wins in North with the A, and leads a top spade.

A.      East plays low.  South discards the 4.  Declarer can then continue with a simple cross-ruff, playing a spade ruff, A, club ruff, spade ruff, club ruff, and diamond ruff, and the K will be the tenth trick.

B.      East covers.  South ruffs, ruffs a club, and leads a second top spade.  If East plays low, South discards the 4 and play continues as in A.  If East covers, South ruffs, ruffs another club, ruffs a low spade, cashes the K, and exits with a club to East, discarding low spades from North.  If East leads a diamond, declarer will take two tricks in the suit, so East does better to lead a spade.  South discards the 4.  If West discards, declarer will win the ♠7 and the A;  and if West ruffs, declarer will take the last two tricks with the A and the last club.

If East returns a club rather than a heart at the third trick, declarer ruffs in North, and leads a top spade, the play reverting to the same line.

Trap:  If South leads a low club at the second trick, East plays the ♣7, letting West win the trick.  West then continues with a diamond to defeat the contract.
