A spot of colour rose suddenly to Mrs. Strickland's pale cheeks.
"What is she like?"
I hesitated a little. I knew that I had a bombshell.
"There isn't a woman."
Colonel MacAndrew and his wife uttered expressions of incredulity, and Mrs. Strickland sprang to her feet.
"Do you mean to say you never saw her?"
"There's no one to see. He's quite alone."
"That's preposterous," cried Mrs. MacAndrew.
"I knew I ought to have gone over myself," said the colonel. "You can bet your boots I'd have routed her out fast enough."
"I wish you had gone over," I replied, somewhat tartly. "You'd have seen that every one of your suppositions was wrong. He's not at a smart hotel. He's living in one tiny room in the most squalid way. If he's left his home, it's not to live a gay life. He's got hardly any money."
"Do you think he's done something that we don't know about, and is lying doggo on account of the police?"
he suggestion sent a ray of hope in all their breasts, but I would have nothing to do with it.
请教老师： 上述对话中，出现了"...If he's left his home, it's not to live a gay life. He's got hardly any money." 这里如何理解if he's left his home=If he has left his home？ 这里在if条件句中用了目前完成时表达了什么样的含义？
(故事背景：He已经离开家了，他目前不在家）
If he's left his home, it's not to live a gay life. He's got hardly any money.
这个if 引导的是让步从句，if = even if.
