“That is correct, Sir Matthew. After I had been in Parkmead for nearly two weeks, I asked the vicar, who had been to visit me every day, to try and find out how Bruce was coping without me.”
“Did you not think it surprising that your husband hadn’t been to see you once during the time you were in hospital?” asked Sir Matthew, who began slowly pushing his cup of coffee toward the edge of the table.
“No. I had threatened to leave him on several occasions, and I don’t think …” The cup fell off the table and shattered noisily on the stone floor. Sir Matthew’s eyes never left Mrs. Banks.
She jumped nervously but did not turn to look in the direction of the broken cup.
“Are you all right, Mr. Casson?” she asked.
“My fault,” said Sir Matthew. “How clumsy of me.”
Casson suppressed a smile. Witherington remained unmoved.
“Please continue,” said Sir Matthew as he bent down and began picking up the pieces of china scattered across the floor. “You were saying, ‘I don’t think …’”
“Oh, yes,” said Mrs. Banks. “I don’t think Bruce would have cared whether I returned to the farm or not.”
“Quite so,” said Sir Matthew after he had placed the broken pieces on the table. “But can you explain to me why the police found one of your hairs on the handle of the axe that was used to dismember your husband’s body?”
“Yes, Sir Matthew, I can. I was chopping up some wood for the stove before I prepared his breakfast.”
“Then I am bound to ask why there were no fingerprints on the handle of the axe, Mrs. Banks.”
“Because I was wearing gloves, Sir Matthew. If you had ever worked on a farm in mid-October, you would know only too well how cold it can be at five in the morning.”
This time Casson did allow himself to smile.
“But what about the blood found on your husband’s collar? Blood that was shown by the Crown’s forensic scientist to match your own.”
“You will find my blood on many things in that house, should you care to look closely, Sir Matthew.”
“And the spade, the one with your fingerprints all over it? Had you also been doing some digging before breakfast that morning?”
“No, but I would have had cause to use it every day the previous week.?
?
“I see,” said Sir Matthew. “Let us now turn our attention to something I suspect you didn’t do every day, namely the purchase of strychnine. First, Mrs. Banks, why did you need such a large amount? And second, why did you have to travel twenty-seven miles to Reading to purchase it?”
“I shop in Reading every other Thursday,” Mrs. Banks explained. “There isn’t an agricultural supplier any nearer.”
Sir Matthew frowned and rose from his chair. He began slowly to circle Mrs. Banks, while Casson watched her eyes. They never moved.
When Sir Matthew was directly behind his client, he checked his watch. It was 11:17. He knew his timing had to be exact, because he had become uncomfortably aware that he was dealing not only with a clever woman, but also an extremely cunning one. Mind you, he reflected, anyone who had lived for eleven years with such a man as Bruce Banks would have had to be cunning simply to survive.
“You still haven’t explained why you needed such a large amount of strychnine,” he said, remaining behind his client.
“We had been losing a lot of chickens,” Mrs. Banks replied, still not moving her head. “My husband thought it was rats, so he told me to get a large quantity of strychnine to finish them off. ‘Once and for all’ were his exact words.”
“But as it turned out, it was he who was finished off, once and for all—and undoubtedly with the same poison,” said Sir Matthew quietly.
“I also feared for Rupert’s safety,” said Mrs. Banks, ignoring her counsel’s sarcasm.
“But your son was away at school at the time, am I not correct?”
“Yes, you are, Sir Matthew, but he was due back for half term that weekend.”
“Have you ever used that supplier before?”
