PART ONE
Earth

Outside, Inside
Returning from an early lunch at an Indian restaurant just a five-minute walk away from E-Branch HQ in the heart of London, Ben Trask sweated inside and out. Inside, from the curry which was still searing his mouth and throat; outside, from the unusually warm May weather. The noonday sun blazed down on him from a sky as vast and blue as the Ionian which he hoped his visitor from another world was enjoying, because Trask sure as hell was not! In fact, ever since Zek Foener and Nathan Kiklu (or Nathan 'Keogh', as the Necroscope preferred to be called now) had gone off to the Greek Islands a few days ago, Trask had been right out of sorts with himself, and with everyone else in his top-secret ESPionage organization.
He thought about the two, worried about them equally ... but for different reasons. About Nathan, because he was probably the most valuable and certainly the most -what, unique? - man in the world; even in two worlds. And about Zek, because he loved her. At his age (Trask snorted), finally to have fallen in love! Not that he was ancient, and he certainly wasn't 'past it', but ... it compJicated matters. And with Zek in the Greek Islands, things seemed even more complicated. That silly old saw which has it: 'out of sight, out of mind', had it backwards as far as Trask was concerned. She was out of sight, all right, but she'd never been more in his mind than right now .. .
And even as he thought it, the thought itself was like an invocation:
Deep water ... the salt sea .. . weeds and sediment
obscuring Trask's vision - no, Zek's vision/ - and the pain in his/her chest ... heart hammering, vision bJurring, lungs screaming for air! Sweet Jesus, she was drowning! And she was Jetting him know about it in the onJy way she could ... for Zek was one of the world's finest telepaths.
BEN! The word exploded into his mind like a bomb. TRY NOT TO FEEL .. . TOO . .. BAD .. . ABOUT ... IT.
'Zek!' he yelled out loud, and could actually taste the water flooding into his/her mouth.
GOOD... BYE... BEN...!
Trask staggered, whirled, fell, and felt his knees slam down hard on the dusty pavement. But it didn't hurt. Nothing hurt except the fact that Zek's telepathic voice was dead in his mind. And that Zek herself-?
Across the road, people were staring. A car's horn blared and its astonished driver gazed down at Trask where he kneeled half-on, half-off the road. Then the car swept on by and people came running, questioning. Someone asked if Trask had been hit. He shook his head, got to his feet and staggered again. A young couple grabbed him, held him upright, and the girl asked, 'Are you all right?'
Numb, he nodded. He was all right, yes. But Zek -?
