Hooters bent down and retrieved a hand grenade and pulled the pin.

Whispering a final prayer, he lobbed it into the middle of the group and ducked back below the stone wall as he did so.

The safety lever flew off and armed the weapon as it landed at the feet of a young man, looking for all the world like a ball thrown by a child.

Reflexively, he bent to pick it up, ready to send it back to its owner.

But it was surprisingly heavy.

‘What’s that?’ said one of his friends.

‘Mierda!’ said the man. ‘I think it’s…’

The grenade detonated, killing him and one other man instantly, and wounding every other person in that group.

It was the signal for the shooting to begin.

The panic was instantaneous and total.

Some dived to the ground.

Others stood and stared at the gunmen, their minds temporarily unable to make their legs move.

Still others ran – only to find that they were running towards the other shooters.

The fat German man was one of the first to die, along with his snotty-nosed son – whom he had scooped up into his arms. His wife went down, too, though their five-year-old daughter survived.

The two pretty young Spanish girls whom Carr had been eyeing up – one of them was shot through the temple, and killed outright, the other through the arm and thigh.

She would bleed to death before help arrived.

The cut-off team were making hay with those who were trying to get off the beach.

Men, women, children.

Flip-flops and shorts and bikinis.

Screaming, shouting.

All the time, the remorseless crack-crack of the weapons.

The first police response came within seconds – a marked Guardia Civil Nissan Patrol had by chance been driving down towards the beach.

Three officers – two men and a woman – debussed, drew their pistols, and started moving towards the sand.

They were immediately spotted and engaged by three men some twenty-five metres to their left.

The female officer advanced gamely towards the three, and managed – with one lucky shot – to take out a tall man in a Hooters New York City T-shirt, before a skinny kid in an Adidas vest put her down with three AK rounds in the neck and shoulder.

The two male cops skidded to a halt. One slipped over in his panic, but in a flash he was up and turning and running, and following his partner, who was already five yards ahead of him, head down, weaving.

Dealing with drunken tourists and shoplifters was one thing: this was quite something else.

They were neither physically nor mentally prepared for it.

20.

A FEW MINUTES’ walk along from the beach, John and George Carr were standing outside a bar, halfway down their first pints of San Miguel.

The place was as tacky as it got and it stank of stale cooking oil.

The street was busy with holidaymakers and loud with thumping bass from a nearby sound system, and the heat was still oppressive despite the overhead parasol.
