There were contradictory accounts of how long it took Samuel to make the trip to Trowbridge, and of whether Peacock caught up with him before or after he summoned Foley. The version in the Somerset and Wilts Journal of 7 July had it that Peacock overtook Kent before he reached Trowbridge, and that Kent returned instantly, while the clergyman rode on to the town to fetch Foley and his men. Since Kent was away for an hour, and Trowbridge was just four or five miles from Road, this left a lot of time unaccounted for. Could Kent have been using that time to dispose of a murder weapon or other evidence? A month later the Journal corrected its original story: Kent was on his way back to Road when Peacock accosted him, it reported, and he had already informed Foley of the loss of the child. This account – which concurred with the first published version of these events, in the Bath Chronicle of 5 July – made the timings more reasonable.
Some of the villagers spoke of Kent as an arrogant, bad-tempered master who was either rude or lascivious towards his servants, more than a hundred of whom were said to have passed through Road Hill House since he had moved in. But Whicher found him a decent, even sentimental man. 'As regards his moral character,' wrote Whicher, 'I cannot find that there is anything against him, and I am informed by the Servants now in the family, and by those who have left that he and Mrs Kent lived in perfect harmony, and one of them (the monthly nurse) stated that she considered him foolishly fond and indulgent towards her, and doatingly fond of the deceased child which I fear led to his untimely death.'
Another suspect was William Nutt, who had seemed to predict his own discovery of Saville's body. He had a grudge against Samuel, who had prosecuted a member of his family for stealing apples from the Road Hill orchard. Some named Nutt as Elizabeth Gough's imagined lover. 'I do not think there are grounds for the suspicion entertained relative to the witness "Nutt" who found the child,' Whicher wrote, 'as it appears very natural that he would have made the remark of "looking for a dead child as well as a living one" as at that time he and Benger had searched other places and were then going to search the privy.' As for the suggestion 'that he was improperly connected with the Nursemaid, there is not the slightest grounds for that suspicion, as she in the first place was not acquainted with him and in the next place I do not suppose she hardly ever spoke to him nor would condescend to speak to him in any way much more as an admirer, as she is rather a superior girl for her station in looks and demeanour, while on the other hand "Nutt" is a slovenly dirty man, weakly, asthmatical, and lame'.
Whicher steadfastly defended Gough's innocence. He said he saw nothing in her conduct to make her a likely suspect. This ignored her strange contradictions about the time at which she became aware that Saville's blanket was missing: at first she said she had noticed before his body was found, then that she noticed only afterwards. But if this was a lie rather than a confusion, it seemed a pointless one. There was no need for Gough to conceal her knowledge that the blanket had been taken – it would have been natural for her to check the bedding carefully. By changing her story, she only drew suspicion to herself. A similar ambiguity hung over her account of why she did not raise the alarm when she noticed Saville was missing at 5 a.m.: her delay seemed odd; yet if she had been guilty, she would surely not have brought it up at all. Some thought it suspicious that Gough had not mentioned Saville's absence to Emily Doel, her assistant, just before seven on the morning of his disappearance; Whicher thought her silence 'seems to tell in her favour', because it indicated that she really did believe the boy's mother had taken him, and that there was no cause for alarm. He also pointed to the innocence implied by the words she used when she roused Mrs Kent at 7.15: 'Are the children awake?'
The police in Isleworth, Gough's home town, had been directed to make inquiries about her character, and the report they sent on 19 July accorded with Whicher's perceptions: she 'is well known to be respectable, quick, kind, good tempered and very fond of children'. As for her supposed lover, the detective could find no evidence 'that she was even acquainted with any male person, either at Road, or the Neighbourhood'.
Some people speculated that Mrs Holley had destroyed Constance's nightdress in order to incriminate the girl and protect William Nutt, who was married to one of her daughters – the fullest version of this theory identified five conspirators: Nutt, Holley, Benger (whom Samuel Kent had apparently once accused of overcharging him for coal), Emma Sparks (the nursemaid who testified about the bedsocks, and had been dismissed by Samuel the previous year) and an unnamed man whom Samuel had prosecuted for fishing in the river. There was little evidence against any of them, other than the mildly suspicious fact that Mrs Holley claimed to have heard a rumour before Monday, 2 July that a nightdress was missing. Whicher had an explanation for this: 'The rumour about the nightdress . . . must have related to Mary Ann's stained nightdress, which the police had confiscated and examined but which had that morning been returned to her.'
On Sunday, Samuel Kent was given permission to visit his daughter in prison. He was accompanied to Devizes, another Wiltshire wool town, by William Dunn, a widowed solicitor born in east London and living in Frome. (Rowland Rodway had resigned as Samuel's legal representative because he believed Constance was guilty; he later agreed to represent Mrs Kent, who must have shared his view.) This case was far outside Dunn's regular remit. In the county court the previous month he had represented a man who had been sold a faulty turnip-cutter, and another whose cow had developed a lump as fat as two fists after being 'pogged' (poked with a stick) by a rival dairy farmer.
When they reached the gaol – designed like a wheel, with the governor's office at the hub and a hundred cells radiating out from it – Samuel found himself unable to face his daughter and sent Dunn to her cell in his stead. His reasons were inscrutable. The Times said that 'the feelings of the father overcame him, and he was unable to undergo the interview', but did not make clear whether these were Samuel's feelings as a father to Constance or to Saville: he might have collapsed under the weight of his pity for Constance, or of his horror at her. The Bath Chronicle echoed the uncertainty: 'he could not bear the ordeal of an interview with his daughter, and, therefore, remained in an adjoining room, while the solicitor conferred with Miss Kent'. It could be that Samuel recoiled from any discussion of his son's death. In the weeks since the murder, his strategy had seemed to be silence. 'Mr Kent has never alluded to the murder to me from first to last,' Elizabeth Gough remarked later. 'The young ladies have, and so has Miss Constance, but not Mr Kent. Master William has frequently cried over it.'
When Dunn visited Constance in her cell, she repeatedly told him that she was innocent. The solicitor sent to a local hotel for a comfortable mattress, to make her week in gaol more pleasant, and arranged for her to be provided with special rations.
A prison officer afterwards briefed the waiting reporters. 'We are credibly informed that Miss Kent's demeanour in the prison was calm and quiet,' said the Western Morning News, 'and that she appeared to be conscious of her innocence and ashamed of being placed in such a position.'
