extra brusqueness and impatience crept into his demeanour, to join forces with the large quantities of brusqueness and impatience which were already there.

They paced down the corridor for a few seconds in silence. Kate was looking for other ways of casually introducing the subject of recent admissions, but was forced to concede to herself that you cannot attempt to introduce the same subject three times in a row without beginning to lose that vital quality of casualness. She glanced as surreptitiously as she could at each door they passed, but most were firmly closed, and the ones that were not revealed nothing of interest.

She glanced out of a window as they walked past it and noticed a van turning into a roar courtyard. It caught her attention in the brief instant that it was within her view because it very clearly wasn't a baker's van or a laundry van. Baker's vans and laundry vans advertise their business and have words like "Bakery" and "Laundry" painted on them, whereas this van was completely blank. It had absolutely nothing to say to anyone nnd it said it loudly and distinctly.

It was a large, heavy, serious-looking van that was almost on the verge of being an actual lorry, and it was painted in a uniform dark metallic grey. It reminded Kate of the huge gun-metal-grey freight lorries which thunder through Bulgaria and Yugoslavia on their way from Albania with nothing but the word "Albania" stencilled on their sides. She remembered wondering what it was that the Albanians exported in such an anonymous way, but when on one occasion she had looked it up, she found that their only export was electricity - which, if she remembered her high school physics correctly, was unlikely to be moved around in lorries.

The large, serious-looking van turned and started to reverse towards a rear entrance to the hospital. Whatever it was that the van usually carried, Kate thought, it was about either to pick it up or deliver it. She moved on.

A few moments later Standish arrived at a door, knocked at it gently and looked enquiringly into the room within. He then beckoned to Kate to follow him in.

This was a room of an altogether different sort. Immediately within the door was an ante-room with a very large window through which the main room could be seen. The two rooms were clearly sound-proofed from each other, because the anteroom was decked out with monitoring equipment and computers, not one of which but didn't hum loudly to itself, and the main room contained a woman lying in bed, asleep.

"Mrs Elspeth May," said Standish, and clearly felt that he was introducing the top of the bill. Her room was obviously a very good one - spacious and furnished comfortably and expensively. Fresh flowers stood on every surface, and the bedside table on which Mrs May's knitting lay was of mahogany.

She herself was a comfortably shaped, silver-haired lady of late middle age, and she was lying asleep half propped up in bed on a pile of pillows, wearing a pink woolly cardigan. Aher a moment it became clear to Kate that though she was asleep she was by no means inactive. Her head lay back peacefully with her eyes closed, but her right hand was clutching a pen which was scribbling away furiously on a large pad of paper which lay beside her. The hand, like the wheelchair girl's mouth, seemed to lead an independent and feverishly busy existence. Some small pinkish electrodes were taped to Mrs May's forehead just below her hairline, and Kate assumed that these were providing some of the readings which danced across the computer screens in the ante-room in which she and Standish stood. Two whitecoated men and a woman sat monitoring the equipment, and a nurse stood watching through the window. Standish exchanged a couple of brief words with them on the current state of the patient, which was universally agreed to be excellent.

Kate could not escape the impression that she ought to know who Mrs May was, but she didn't and was forced to ask.

"She is a medium," said Standish a little crossly, "as I assumed you would know. A medium of prodigious powers. She is currently in a trance and engaged in automatic writing. She is taking dictation. Virtually every piece of dictation she receives is of inestimable value. You have not heard of her?"

Kate admitted that she had not.

"Well, you are no doubt familiar with the lady who claimed that Mozart, Beethoven and Schubert were dictating music to her?"

"Yes, I did hear about that. There was a lot of stuff in colour supplements about her a
