To celebrate the occasion, Cook asked a number of his friends to dine with him at the hotel in Shrewsbury. That evening Palmer was observed holding a tumbler up to the light outside his bedroom, and he then went into the other room where Cook was talking to his friends. After drinking some brandy, Cook became violently ill, and a doctor was sent for. Cook said he had been given something by Palmer, and gave his money into the charge of one of his friends, who next day returned it to him. Notwithstanding his suspicions, Cook returned with Palmer to Rugeley, and put up at an inn there near Palmer's house. He was there visited several times by Palmer, who gave him coffee and broth, both of which made him violently sick. He was attended by a local medical man, who was very old, and, acting on Palmer's suggestion, this doctor prescribed morphine pills for the sick man. Palmer went with the doctor to his surgery, helped him in the preparation of the pills, and undertook to see that the patient took them. Accordingly he went round to the inn the same night, and persuaded Cook, who was unwilling to have anything to do with them, to take the pills. Within fifteen minutes he had died, after showing all the symptoms of strychnine poisoning. After Cook's death, his stepfather came to Rugeley, and made inquiries as to the cause of death. Certain circumstances drew suspicion upon Palmer, and this was strengthened when it was found that on several occasions he had bought strychnine, and that immediately after Cook's death he had been seen examining his pockets and searching under the pillow of the bed. When asked whether there were not some sporting debts due to Cook, he denied that there were any, and it was significant that the betting book of the deceased man had disappeared. It was further discovered that Palmer had since the death paid over considerable sums of money to his creditors, and that he had induced the old doctor who had been in attendance upon Cook to sign a certificate giving apoplexy as the cause of death. A post-mortem examination was held, at which Palmer, although under suspicion, was allowed to be present. When the portion of the stomach was sealed up in a bottle, Palmer removed it to another part of the room while the attention of the doctors was otherwise occupied, and it was found that he had cut two slits in the parchment cover, and had attempted to get rid of the contents. Subsequently he offered a bribe of £10 to the driver who was to take the doctors to the station if he would upset the carriage and break the jar. The evidence of the doctors called by the Crown left little doubt as to death having been caused by strychnine poison, and although a number of medical men gave evidence on behalf of Palmer, their opinions were conflicting and inconsistent, and, as the judge pointed out, were obviously aiming at an acquittal at all cost.
