Peril sharpens the intellect. Archie's mind as a rule worked in rather a languid and restful sort of way, but now it got going with a rush and a whir. He glared round the room. He had never seen a room so devoid of satisfactory cover. And then there came to him a scheme, a ruse. It offered a chance of escape. It was, indeed, a bit of all right.

Peter, the snake, loafing contentedly about the carpet, found himself seized by what the Encyclopaedia calls the "distensible gullet" and looked up reproachfully. The next moment he was in his bag again; and Archie, bounding silently into the bathroom, was tearing the cord off his dressing-gown.

There came a banging at the door. A voice spoke sternly. A masculine voice this time.

"Say! Open this door!"

Archie rapidly attached the dressing-gown cord to the handle of the bag, leaped to the window, opened it, tied the cord to a projecting piece of iron on the sill, lowered Peter and the bag into the depths, and closed the window again. The whole affair took but a few seconds. Generals have received the thanks of their nations for displaying less resource on the field of battle.

He opened the-door. Outside stood the bereaved woman, and beside her a bullet-headed gentleman with a bowler hat on the back of his head, in whom Archie recognised the hotel detective.

The hotel detective also recognised Archie, and the stern cast of his features relaxed. He even smiled a rusty but propitiatory smile. He imagined--erroneously--that Archie, being the son-in-law of the owner of the hotel, had a pull with that gentleman; and he resolved to proceed warily lest he jeopardise his job.

"Why, Mr. Moffam!" he said, apologetically. "I didn't know it was you I was disturbing."

"Always glad to have a chat," said Archie, cordially. "What seems to be the trouble?"

"My snake!" cried the queen of tragedy. "Where is my snake?"

Archie, looked at the detective. The detective looked at Archie.

"This lady," said the detective, with a dry little cough, "thinks her snake is in your room, Mr. Moffam."

"Snake?"

"Snake's what the lady said."

"My snake! My Peter!" Mme. Brudowska's voice shook with emotion. "He is here--here in this room."

Archie shook his head.

"No snakes here! Absolutely not! I remember noticing when I came in."

"The snake is here--here in this room. This man had it in a bag! I saw him! He is a thief!"

"Easy, ma'am!" protested the detective. "Go easy! This gentleman is the boss's son-in-law."

"I care not who he is! He has my snake! Here--' here in this room!"

"Mr. Moffam wouldn't go round stealing snakes."

"Rather not," said Archie. "Never stole a snake in my life. None of the Moffams have ever gone about stealing snakes. Regular family tradition! Though I once had an uncle who kept gold-fish."
