The maid Walker was the only person who gave any direct evidence against him, and she said that she heard the door shut at a quarter past eleven, and that on going downstairs directly afterwards she found that both he and the deceased had left the house. But he would prove that he had entered the Glove Inn as the town clock struck eleven, that he had stayed there a quarter of an hour, that after he had done several things at his lodgings he had gone to bed by twelve, and had not gone out again that night. He had sent to fetch his horse from Mrs. Stout's house on Tuesday morning, as was only prudent, but he had told the man whom he sent that he would not want it till the next day, when he was going into Essex with the rest of the circuit, which he did.
He had not heard that his name was connected with Mrs. Stout's death till two months after the event; and the prosecution had in fact been set on foot by the Quakers, who were scandalised at the idea of one of their number committing suicide, and the political opponents of his father and brother in the town.
Cowper went on to explain that he always had the offer of a share in his brother's lodgings, which were some of the best in the town, whenever the latter went circuit, 'which out of good husbandry I always accepted.' At the time of the last circuit, when the present case arose, Parliament was sitting, and his brother 'being in the money chair,' could not attend. As Cowper had been invited to lodge with Mrs. Stout during the assizes and wished to accept the invitation, he asked his brother to ask Barefoot, the keeper of his lodgings, to dispose of them if he could. The brother said he would do so 'if he could think on it,' and accordingly Cowper went down to Hertford intending to lodge with Mrs. Stout unless his brother had failed to write to Barefoot. On arriving at Hertford he found that his brother had not written to Barefoot, and that the rooms there were ready for him. He accordingly stayed there, sent to the coffee-house for his bag, and took up his lodging at Barefoot's as usual. As soon as he had done this, the maid Walker came round from Mrs. Stout's to invite him to dinner there. He accepted the invitation, and also a further invitation to come again in the evening; but he did not agree to sleep there. When he came the second time he paid the deceased the interest on her mortgage, some six pounds odd, in guineas and half-guineas, which money was found in her pocket after she was drowned. He wrote a receipt for the money, which she refused to sign; she pressed him to stay there that night, which he refused to do.
He then went on:—
'My lord, I open my defence shortly, referring the particulars to the witnesses themselves, in calling those who will fully refute the suppositions and inferences made by the prosecutor, whom first, my lord, I shall begin with, to show there is no evidence of any murder at all committed; and this I say again, ought to be indisputably made manifest and proved, before any man can be so much as suspected for it.
Hatsell, Baron—Do not flourish too much, Mr. Cowper; if you have opened all your evidence, call your witnesses, and when they have ended, then make your observations.
Mr. Cowper—Then, my lord, I will take up no more of your time in opening this matter. Call Robert Dew. (Who appeared.) When Mrs. Sarah Stout drowned herself, was not you a parish officer?
Dew—I was. I was next house to the Coach and Horses; and about six o'clock came a little boy (Thomas Parker's boy), and said there was a woman fallen into the river. I considered it was not my business, but the coroner's, and I sent the boy to the coroner, to acquaint him with it, and the coroner sent word by the boy, and desired she might be taken out; so I went to the river, and saw her taken out: she lay in the river (as near as I could guess) half a foot in the water; she was covered with water; she had a striped petticoat on, but nothing could be seen of it above water. I heaved her up, and several sticks were underneath her, and flags; and when they took her out, she frothed at the nose and mouth.
Cowper—How was she? Was she driven between the stakes?
Dew—She lay on the right side, her head leaning rather downwards: and as they pulled her up, I cried, 'Hold, hold, hold, you hurt her arm'; and so they kneeled down and took her arm from the stakes.
