I did not see him for several days after that, but one evening, when I was sitting in the cafe, reading a paper, he came up and sat beside me.

"You haven't hanged yourself after all," I remarked.

"No. I've got a commission. I'm painting the portrait of a retired plumber for two hundred francs."

"How did you manage that?"

"The woman where I get my bread recommended me. He'd told her he was looking out for someone to paint him. I've got to give her twenty francs."

"What's he like?"

"Splendid. He's got a great red face like a leg of mutton, and on his right cheek there's an enormous mole with long hairs growing out of it."

Strickland was in a good humour, and when Dirk Stroeve came up and sat down with us he attacked him with ferocious banter. He showed a skill I should never have credited him with in finding the places where the unhappy Dutchman was most sensitive. Strickland employed not the rapier of sarcasm but the bludgeon of invective. The attack was so unprovoked that Stroeve, taken unawares, was defenceless. He reminded you of a frightened sheep running aimlessly hither and thither. He was startled and amazed. At last the tears ran from his eyes. And the worst of it was that, though you hated Strickland, and the exhibition was horrible, it was impossible not to laugh. Dirk Stroeve was one of those unlucky persons whose most sincere emotions are ridiculous.

请教老师：

这一句He showed a skill I should never have credited him with in finding the places where the unhappy Dutchman was most sensitive. 中，

I should never have credited him 是虚拟语气吗？ 如果是的话，那意思就是：我那时（在当时，在过去）是相信他的。 对吗？ 还有with的宾语是a skill吗？ 后面in finding...也是a skill的后置定语吗？

就是说，a skill有2个后置定语？  麻烦老师分析一下句子成分，句意, 这一句怎么翻译呢？

非常感谢！
