"Not at all. Figuratively speaking it has been whitewashed. It's become a show place—a monument historique. This is interesting information which Fenton sends, but if it came from any one else, I should say he had dreamed it. He may be giving us the chance of an important coup. Wait a few minutes, and I'll have this thing attended to, Lord Ernest. But you look upset. Is it that you haven't had lunch, or are you worrying about the ladies?" "Both," I answered with a sickly grin. "Not that I mind about lunch. I couldn't have eaten if I'd had the time."

"You haven't as much belief as I have, in your friend," remarked Jarvis Pasha, "if you think he'd let them come to harm." "They're all in the same box, apparently," I excused my lack of faith.

"Trust Fenton!" said the Head of the Police. "He was sharp enough to find the needles in the haystack, and he's smart enough and strong enough to take care of them when they're found."

On this, Jarvis Pasha went out and left me to my reflections, which rushed to the House of the Crocodile. Every one who has read or heard stories of native Cairo, knows the House of the Crocodile, in the Street of the Sisters, and how, in the later days of Mohammed Ali, people scarcely dared to name it aloud. The "Tiger" Defterdar Ahmed built it, for that beautiful Tigress, Princess Zohra, favourite daughter of Mohammed Ali, who married her off to the fierce soldier when she became too troublesome at home. Zohra had loved a young Irish officer who was murdered for her sake, and had no true affection to give Ahmed or any other. She hated all men because of the murderer, her own nephew, and vowed that since her love had cost the life of the one who had her heart, others who dared to love her must pay the same price. When Ahmed died suddenly, soon after the wedding, those who had heard of Zohra's vow (and there were many in the harems) whispered "poison." Never again did the Princess drive out to see the women she knew; and those who had been her friends were sent away from the door of the dead Ahmed's palace, over which he had suspended for "luck," a huge crocodile killed in the far south. But Zohra was beautiful, with strange eyes which drew love whether she asked for it or not; and sometimes a small lattice would open in a bay of one of those windows of wooden lace whose carving was known as mushrbiyeh work because shirib, or sherbet, used to be placed there to cool. Out of the lattice would look a wonderful face, as thinly veiled as the moon by a mist, and then it would vanish so quickly that a man who saw, half believed that he had dreamed. But the eyes of the dream seemed to call, and could not be forgotten, any more than the song of a siren can cease to echo in ears which once have heard.

After the beginning of Zohra's widowhood, the noblest and handsomest youths of Cairo began mysteriously to disappear. They would be well and happy one day, and the next they would be gone from the places that knew them. By and by their bodies would be found in a canal; always the same canal, near the water gate of the House of the Crocodile. Then the vow of the Princess was remembered: but there was no English rule in those days, and the police shut their ears and eyes where a daughter of Mohammed Ali was concerned. Mothers and sisters of handsome young men shuddered and begged those they loved never to pass through the dark Street of the Sisters (Sharia el Benât) where the crocodile grinned over the door, and the vision of a face looked down from a latticed window. The women thought of the water gate at the back of the house; the little children, who had heard secret words spoken, thought of the crocodile, and ran crying past the house; but the handsome young men thought only of the face, and each one said to himself, "She will not make me pay the price." Still, as years went on, bodies were seen in the water from time to time, with a tiny purple spot over the heart to show the curious that death had not come from drowning. And some, who looked for lost ones, could not reclaim them from the canal, for bodies were not always found. As time passed, it seemed to people who hurried by the house in the narrow street, that the crocodile grew larger and larger. It was said that it had been fed on the children of men Tiger Ahmed had murdered in Sennaar.

None dared to say what they believed of Princess Zohra, but when, after a long imprisonment by her nephew Abbas, in the House of the Crocodile, she escaped to Constantinople, nobody would live where she had lived, and the palace fell almost into ruin.

This was the story of the house where Monny Gilder and Rachel Guest and Anthony Fenton were now. I had heard it talked about by our Arab servants when I was a child, and had never forgotten, though scarcely since then had I thought of the tale, until the remembered name and the horrors attached to it jumped into my mind on reading Anthony's letter. What had happened in the House of the Crocodile since Zohra's day, I did not know; but because of the old story it seemed more sinister that my friends should appeal for help from that place than from any other in Cairo.

I was not left long alone. Five minutes after Jarvis Pasha went out of the room to "arrange things" according to Fenton's request, he sent me a man with whiskey and soda, and biscuits. I drank gladly, and ate rather than seem ungrateful. But there was a lump in my throat which would stick there, I knew, until those three were away from the House of the Crocodile. I was still crumbling biscuits when Jarvis Pasha came briskly back.

"Well," he asked, "are you braced up now? If you'd like to be in this business, you can. I'm sending a white superintendent with my police to raid the house, on the strength of Fenton's letter to you, though until now the place hasn't been suspected. As I said, it's been a 'show' house, for some years—ground floor and first story in repair, just as in Zohra's day—upper floors ruinous, and the public not admitted there. If anything queer's going on, it must be in the forbidden part: and the caretaker is mixed up in the show. A pity you felt bound to let Fenton's messenger off! You can go with my superintendent, Allen, and reach your friends as soon as my men do. Allen has instructions to let Fenton and the ladies, if they're found there, slip away, and it's best for you to be on the spot to save mistakes in identification. Also I've ordered a closed arabeah to wait for you, as near as possible—my men will show you where. You'll know it for certain by a red camellia on the Arab driver's European coat. And by the way, take this Browning, in case of an attack; which I don't anticipate."

As Jarvis Pasha spoke, he opened the door, and summoned in a brown young Britisher wearing the tarboosh which denotes "Gyppy" officialdom. Evidently Allen was prepared for me as I for him, and we started off together on foot, for it seemed that our destination was not far away. We walked swiftly through the crowded Mousky (once the fashionable part of Cairo, before the tide flowed to the modern Isma'iliya quarter), and after a few intricate turnings plunged into a still, twilight region. The streets through which we passed were so narrow, and the old houses so far overhung the path that the strip of sky at the top of the dark canyon was a mere line of inlaid blue enamel flecked with gold. The splendid mushrbiyeh windows thrust out toward each other big and little bays, across the ten or twelve feet of distance which parted them, as if to whisper secrets; yet the delicate wooden carvings skilfully hid all that they wished to hide, and only suggested their secrets.
