She couldn't risk letting him stay with her now.

Every instinct warned him not to risk letting this happen.

But I do know we cannot risk letting you become lost.

But she could not risk letting them say goodbye to him.

"You would risk letting your brother's killer go free if I refuse?"

Yet, he could not risk letting his quarry get away.

And could he risk letting the thing in his dream find her?

She couldn't risk letting him find out about her past.

I don't think we dare risk letting them meet the way they plan to now.
