Why the plan needed a liar
An enormous horse abandoned on the beach fools nobody on its own. The Trojans argued about what to do with it: burn it, push it off a cliff, cut it open.
They needed someone to explain what it was, and the explanation had to hold. That is why Odysseus' plan was not just the horse: it was the horse plus a witness.
Sinon's lie
Sinon let himself be tied up and brought before Priam. His story had three layers, and that is the craft of it.
First, he made himself the victim: he said the Greeks had decided to sacrifice him for favourable winds, and that he had escaped. That made him an enemy of his own countrymen.
Second, he gave the horse a reason: an offering to Athena, to make up for a sacrilege.
Third, and this is the masterstroke, he told them not to bring it in. He explained that the Greeks had built it deliberately too large for the gates, because if the Trojans ever got it inside the city, Troy would be invincible.
By telling them they could not, he made them want to. The Trojans pulled down part of their own wall to fit it through.
The two who warned them
Laocoon, a priest, distrusted it and drove a spear into the horse's flank. The line attributed to him, "I fear the Greeks even when they bring gifts", has outlived twenty-eight centuries. Two serpents came out of the sea and strangled him along with his sons. The Trojans read it as punishment for insulting the offering.
Cassandra warned them too. Nobody ever believed her, because that was precisely her curse: to see the future and be ignored.
That is the cruellest part of the episode: Troy did not fall for want of warnings. It fell because it got two and dismissed both.

Quick questions
Who was Sinon in Greek mythology?
The Greek who stayed on the beach on purpose to be captured by the Trojans and talk them into hauling the wooden horse inside. He is not a warrior: his weapon is a well built story, and it works better than ten years of siege.
Why did the Trojans take the horse in if they suspected it?
Because Sinon told them not to. He explained that the horse had been made deliberately too big for the gates, and that if they ever got it inside, the city would be invincible. He turned the prohibition into a prize, and they tore down their own wall.
Did the Trojan horse really exist?
There is no archaeological evidence. Homer does not even tell it in the Iliad: it appears in passing in the Odyssey and in detail much later, above all in Virgil's Aeneid. The city of Troy did exist; the horse belongs to the story, not to the record.
