something about a gadget, Tommy. At--80 Hosain, you said?" Coghlan nodded. "Yes. Duval and Lieutenant Ghalil said they were going to make inquiries there." "After dinner," suggested Laurie, "we could take the car and go look at the outside, anyhow? I don't think Father has anything planned. It would be interesting--" "Not a bad thought," said Mannard. "It's a pleasant night. We'll all go." Laurie smiled ruefully at Coghlan. And Coghlan resolutely assured himself he was pleased--it was much better for him not to be anywhere with Laurie, alone. But he was not cheered in the least. Mannard pushed back his chair. "It's irritating!" he grunted. "I can't figure out what they're driving at! By all means let's go look at that infernal house!" They went up to Mannard's suite on the third floor of the Petra, and he telephoned and ordered the car he'd rented during his stay in Istanbul. Laurie put a scarf over her head. Somehow even that looked good on her, as Coghlan realized depressedly.Appolonius the Great had blandly assumed an invitation and continued to talk about his political enterprise of bribery.

Mannard came storming up the steps. He glared about him, breathing hard. He was the very opposite of the typical millionaire just then. He looked hardboiled, athletic, spoiling for a fight. "My dear friend!" gasped Appolonius. "What happened?" "Somebody tried to throw me down-stairs!" growled Mannard balefully. "They grabbed my foot and heaved! If I'd gone the way I was thrown--if I hadn't handled myself right--I'd have gone over the stair-rail and broken my blasted neck!" He glared about him. But there were only the four of them in sight.
