She was now feeling horribly frightened. She strained her ears in vain for a sound. The whole house seemed wrapped in a grave-like quiet. The smile had never left Mr. Schulz’s face. But it was a cruel, wolfish grin without a ray of kindliness in it. The girl felt her heart turn cold within her every time her eyes fell on the mask-like face. Mr. Schulz shrugged shoulders. “Since you insist ...” he remarked. “But I think it is scarcely fair on our friend Dulkinghorn. The letter is in the safe in my office next door. If you come along I will get it out and show it to you ...” He spoke unconcernedly, but stiffly, as though to emphasize the slight put upon his dignity. One hand thrust jauntily in his jacket pocket, he stepped across the carpet to the door with the blue curtain. He opened it, then stood back for the girl to pass in before him. “After you!” he said. He had placed himself so close to the doorway that the black fox about her neck brushed his face as she passed. Suddenly a warm, sickly whiff of some sweet-smelling odour came to her. She stopped on the instant, irresolute, alarmed. Then a dank hand was clapped on her face, covering nostrils and mouth with a soft cloth reeking with a horrible cloying drug. An arm with muscles like steel was passed round her waist and held her in a vice-like grip against which she struggled in vain. She felt her senses slipping, slipping ... CHAPTER XXIII. TWO’S COMPANY ... On the pavement opposite the post-office stood one of those high pillars which are commonly used in Continental cities for the display of theatre and concert advertisements. Robin instantly stepped behind it. It was not that he wished to avoid being seen by Jeekes as much as that he had not decided in his mind what course he had best pursue. From behind the cover of the pillar he mustered his man. The little secretary looked strange and unfamiliar in a sporting sort of travelling ulster of a tawny brown hue and a cap of the same stuff. But there was no mistaking the watery eyes, the sharp nose, the features. He had obviously not seen Robin. His whole attention was rivetted on the street. He kept peering nervously to right and left as though expecting some one. Suddenly he stepped forward quickly to the kerb. Then Robin saw an open car detach itself from the press of traffic in the square and, driven very fast, approach the post-office. It was a large car with a grey body; a sallow man wearing a black felt hat sat at the wheel. The car drew up at the kerb and halted within a few feet of the advertisement pillar. Robin backed hastily round it to escape observation. He had resolved to do nothing until he had ascertained who Jeekes’s friend was and what business the secretary had with him. “It’s all right,” Robin heard the man in the car say in English; “I telephoned the girl and she’s coming. What a piece of luck, eh?” Robin heard the click of the car door as it swung open.
