behind a tree in Eaton Square for the night. It seemed so obvious: with Miss Crush out at Richmond the Minton vase was there for the taking. Too obvious, perhaps? Thackeray was going to say some strong words about that in the morning, for the plain fact was that the man Cribb suspected of the burglaries was not in Belgravia at all. He had just let himself in through the back door of Dr Probert’s residence in Richmond.
Cribb had followed him there from central London, pursued him in a cab as far as Richmond Bridge and tracked him on foot the rest of the way. He had rarely been so surprised as when the trail led clean through Kensington High Street and on to Hammersmith, Chiswick and Richmond.
And now his suspect had confidently entered Probert’s house by the back door and stepped inside. What in the name of sanity were the servants doing to leave the door unlocked? Curiously, there wasn’t a light on in the basement. The only lights in the house were at the front, on the ground floor, where the seance was presumably taking place, and a small window at the top, where the timid Mrs Probert must have gone for refuge.
Probert wasn’t going to welcome a detective-sergeant on the premises this evening and nor was Jowett, but Cribb knew which way duty lay. Allowing his quarry half a minute to get up the back stairs to the gallery of classical subjects, he followed by the same route.
When he reached the door of the gallery, he found that he had made a second miscalculation. The door was locked, and the man he was pursuing was nowhere within sight or hearing.
DR PROBERT’S EDISON-SWAN lamps were not only more powerful than gas; they lit the room in full brilliance the moment the switch was turned on. The sitters blinked as their optic muscles strained to adapt to the new conditions, but the discomfort was a fair exchange for a clear sight of the room. During the seance, Jowett had felt an increasing urge to check the position of the furniture and the proximity of the walls and ceiling. It was more than a mere wish to orientate himself; it was a need to reaffirm that furniture, walls and ceiling were actually there at all.
‘Would anyone care for another drink?’ asked Probert, breaking the uneasy silence.
‘A small gin neat wouldn’t come amiss, since you mention it, Doctor,’ said Miss Crush.
‘If I may say so,’ said Strathmore, ‘it would be wiser if we all refrained from further consumption of alcohol until after the second experiment, in the interests of science. I shall, of course, be writing a full report of tonight’s events for the Proceedings of my Society. One would not wish to report that certain of the participants had indulged themselves to the extent of a sherry followed by an undiluted gin. It would tend to detract somewhat from the authority of the report.’
‘You have a good point there, Strathmore,’ said Probert. ‘What do you say, Miss Crush?’
‘Oh, a very pertinent point, Doctor. I had no idea that we might be reported in the Proceedings. ’ She smiled coyly in Strathmore’s direction. ‘Will you mention any of us by name, Mr Strathmore?’
‘With your permission, madam, with your permission. I have a notion that my report will be read and discussed in scientific societies all over the world when the importance of what is happening here this evening is generally known.’
‘Then I shall definitely forego the gin,’ declared Miss Crush.
‘In that case, I think we might proceed without delay to prepare the apparatus for the second experiment. I trust that everyone is still prepared to co-operate?’ Dr Probert looked speculatively round the table, leaving the eye of his prospective son-in-law till last.
Captain Nye sniffed. ‘It had better be conducted in a more decent manner than events so far tonight. I won’t have my fiancée put to any more embarrassment, I promise you.’
‘It’s quite all right, William,’ Alice assured him, taking his arm.
‘I’ll be the
