stealthily

There was no more to do in the room, so the poisoner retired stealthily, as though fearing to hear the sound of her own footsteps; but as she withdrew she still held aside the curtain, absorbed in the irresistible attraction always exerted by the picture of death, so long as it is merely mysterious and does not excite disgust.

One of the Mice, peeping stealthily out, saw her and said, “Ah, my good madam, even though you should turn into a meal-bag, we will not come near you.”

He looked stealthily all round him.

She had a good chance to do so, for the said Gilbert Blythe was absorbed in stealthily pinning the long yellow braid of Ruby Gillis, who sat in front of him, to the back of her seat.
